6 packs of tuna fish are sold per hour. If the sales are made for 15 hours, the total number of packs sold is 4=6*15 = 90 packs. At $60 per pack, during a high season, the total sales in 15 hours are 90*$60 = $5400 4 packs of tuna fish are sold per hour. If the sales are made for 15 hours, the total number of packs sold is 4*15 = 60 packs. At $60 per pack, during a low season, the total sales in 15 hours are 60*$60 = $3600 The amount of money that is made after 15 hours during a high season than a low season is $5400-$3600 = $1800

Carmen earned 3 * $4 = $12 at the green house. She earned 2 * $3.50 = $7 for the mints. She earned $7 + $5 = $12 at the yellow house. She earned 9 * $2 = $18 at the brown house. So, Carmen earned a total of $12 + $12 + 18 = $42.

First figure out how many total flowers Martha is going to buy by dividing her total spending by the price per flower: $2700 / $15/flower = 180 flowers Now figure out how many flowers are in each centerpiece by dividing the total number of flowers by the number of centerpieces: 180 flowers / 6 centerpieces = 30 flowers / centerpiece Now figure out how many orchids are in each centerpiece by multiplying the number of roses per centerpiece by 2: 8 roses/centerpiece * 2 = 16 orchids/centerpiece Now subtract the number of roses and orchids per centerpiece from the total number of flowers per centerpiece to find the number of lilies per centerpiece: 30 flowers - 16 orchids - 8 roses = 6 lilies

The total cost for the devices he bought on Monday is 2*20= 40 The total cost for the devices he bought on Tuesday is 4*20 = 80 The total cost of these devices is 80+40= 120 Linus sold each mobile device he bought for $20 x 2 = $40. So, he earned $40 x 2 = $80 for the two devices he bought last Monday. And he earned $40 x 4 = $160 for the 4 devices he bought last Tuesday. The total amount of sales he made were worth 160+80 =240 Linus earned 240-120 =$120

One year is 12 months, so during the first year, Kate spent $5/month * 12 months/year = $60/year on the tickets. After that, she went to the museum for 3 years - 1 year = 2 more years. During this time, she visited the museum 2 years * 4 visits/year = 8 visits. She had to pay the higher price of $7, so she spent $7/visit * 8 visits = $56 in two last years. In total Kate paid $56 + $60 = $116 during 3 years.

Each raised bed is 8 feet long, the same as the planks, so the long sides of the beds will each be 1 plank long. Each raised bed is 2 feet wide, or 2/8 = 1/4 the length of the planks, so the short sides will each be 1/4 plank long. Each bed is 2 feet tall, and the planks are 1 foot wide, so each side will need 2 pieces of lumber of the same length. So each bed will require 2 * 2 * 1.25 = 4 * 1.25 = 5 planks of wood. Bob wants to build 10 raised beds, so he will need 10 * 5 = 50 planks of lumber.

The material cost 600+300=$900 The premium came out to 900*.3=$270 So the total cost was 900+270=$1170

If Calen lost 10 pencils, which left him with 10 pencils, then Calen originally had 10+10=20 pencils. Calen originally had 5 more pencils than does Caleb, and thus Caleb has 20-5=15 pencils. Let's let "x" represent the number of pencils owned by Candy. Since Caleb has 3 less than twice as many pencils as does Candy, then (2*x)-3=15. This simplifies to 2*x=18. Thus, the number of pencils owned by Candy is x=9 pencils.

The group was able to sell 20 x 8 = 160 candy bars. So, they got 160 x $0.5 = $80 from their candy bars sales.

Melanie starts with 1 slice of bread that she tears in half, making 2 halves. She takes both of those halves and tears them each in half, 2 halves x 2 more halves in half = 4 pieces per slice of bread. Melanie is using 2 slices of bread x 4 pieces each = 8 pieces overall to add to the blender.

Jenna will drive 200 miles at a rate of 50 miles per hour, so she will drive for 4 hours. Her friend will drive 100 miles at a rate of 20 miles per hour, so Jenna's friend will drive for 5 hours. They will spend a total of 60 minutes on breaks because 30 minutes + 30 minutes = 60 minutes. Thus, they will spend 1 hour on breaks because there are 60 minutes in an hour. The road trip will take a total of 1+4+5 = 10 hours.

Deliberation ended up taking 6 * 24 = 144 hours That means they spent 144 / 16 = 9 days in deliberation The trial lasted 2 * 4 = 8 days So he spent 2 + 8 + 9 = 19 days on jury duty
