First find how many ml of water Jason needs for 1 gram of charcoal: 30 ml / 2 grams = 15 ml/g Then divide the amount of water Jason uses by the amount of water per gram of charcoal to find how much charcoal he uses: 900 ml / 15 ml/g = 60 g

First, the shop is open 12 hours * 60 minutes = 720 minutes per day. So, 720 / 30 = 24 women's T-shirts sold per day. The shop earns 24 * $18 = $432 selling women's T-shirts per day. Similarly, 720 / 40 = 18 men's T-shirts are sold per day. The shop earns 18 * $15 = $270 selling men's T-shirts per day. The shop earns $432 + $270 = $702 per day selling T-shirts. The shop earns $702 * 7 = $4914 per week.

Twice the number of hours in a typical earth day is 24*2=48 hours. Eight hours less than twice the number of hours in a typical earth day is 48-8=40 hours. If the distance between these two planets is 4,000 parsecs, then the average speed on this voyage was 4000/40=100 parsecs per hour.

They ran 2,400 meters because 24 laps x 100 m/lap = 2400 m They ran 200 meters per minute because 2400 m / 12 min = 200 m/min For every minute they ran they earned an average of $7 because $3.5/100m x 200 m/min = $7/min

20 gallons = 160 pints 160/80 = 2 pints 3.5 * 2 pints = 7 pints Geraldo drank 7 pints of tea.

On the second day, Maria sold 30 * 2 = 60 tulips. She also sold 20 * 2 = 40 roses the second day. On the third day, Maria sold only 10/100 * 60 = 6 tulips. Over these three days Maria sold 30 + 60 + 6 = 96 tulips. She also sold 20 + 40 + 16 = 76 roses. So on the tulips Maria earned 96 * 2 = $192. And on roses Maria earned 76 * 3 = $228. In total, over these three days, Maria has earned 192 + 228 = $420.

If Maude's age is 8 by the time Anne's age is four times Emile's age, Emile will be six times as old as Maude, which totals 6*8 = 48 years. If Emile's age is 48 years old by the time Anne's age is twice her number, Anne will be 2*48 = 96 years.

On the first three days, towing ten cars a day, the tow truck pulled 3*10 = 30 cars. It pulled four fewer cars each day, which is 10-4 = 6 cars on the remaining days. If it pulled ten cars for three days and four less on the remaining days, then it pulled for 7-3 = 4 days, four cars less each day. For the four days, the car pulled 6*4= 24 cars. The total number of cars it pulled that week is 24+30 = 54 cars.

The trip back was 30*.2=6 miles longer than the trip there. So it was 30+6=36 miles. So the total drive was 30+36=66 miles. That means she drove for 66/44=1.5 hours. She stayed with her friend 30/60=.5 hours. So the total time was 1.5+.5=2 hours.

The ticket price increase is $102 - $85 = $17 So there is 17/85 x 100% = 20% increase of price.

Each free throw counts as 1 point, so 5 successful free throws means she scores 5*1= 5 points Each 3 pointer counts as 3 points, so this means Liz scores 3*3= 9 points from 3 pointers Each jump shot counts as 2 points, meaning Liz scores 4*2=8 points of jump shots. Liz's opponents score 10 points during the quarter, meaning their lead is 30 points in total before accounting for Liz's scoring. Liz scores a total of 5+9+8=22 points in the quarter. This amount is subtracted from the lead of Liz's opponents, meaning they win by 30-22= 8 points.

First find how many eggs per minute the owner can clean up: 60 seconds/minute / 15 seconds/egg = 4 eggs/minute Then divide the total number of eggs by the number of eggs cleaned per minute to find how long the owner spends cleaning them up: 60 eggs / 4 eggs/minute = 15 minutes Then find the total time the owner spends cleaning up toilet paper: 7 rolls * 30 minutes/roll = 210 minutes Finally, add that amount to the egg cleaning time to find the total cleaning time: 210 minutes + 15 minutes = 225 minutes

With a garden hose that fills at a rate of 1.6 gallons per minute, and a hole that leaks at 0.1 gallons per minute, the net fill rate becomes 1.6-0.1=1.5 gallons per minute. Therefore, to fill a 60-gallon pool, it will take 60/1.5=40 minutes.

Let's say Jason invested x amount of money. Since Jason started investing, he has earned the same amount he invested twice over in 5 months, meaning he has earned x+2*x=$90 This evaluates to 3x=$90 The total amount of money that Jason invested is x=$90/3 Jason invested x=$30 The total amount of money that Jason has earned from his investments is $90-$30=$60 If he earned an equal amount of money from the investment in five months, his monthly returns is 60/5=$12

If Peter's age is currently half of his mother's age, who is 60, Peter is 1/2*60 = 30 years old. In four years, Peter will be 30+4 = 34 years old. Since Peter's age in four years will be twice Harriet's age, Harriet will be 34/2 = 17 years old in four years. Currently, Harriet is 17-4 = 13 years old.

Abe is spending a third of his budget on food, so he spends $3000 / 3 = $1000 on food. He spends a quarter of his budget on restaurant supplies, so he spends $3000 / 4 = $750 on supplies. Thus, he spends $3000 - $1000 - $750 = $1250 on employee wages every month.
