To get the number of people at Taylor's party, we'll assume there were n people at his party. The total number of people at Ryan's party is 4*n, four times the number of attendees at Taylor's party. Combined, there were 4n+n = 240 people at both parties. This translates to 5n=240. The total number of people at Taylor's party is n=240/5 There were n=48 people at Taylor's party. Since Ryan's party was 4 times as huge as Taylor's party, at Ryan's party, there were 48*4 = 192 people.

When Samantha paid $300 in 30 equal monthly installments, she paid a total of $9000 Since the higher purchase is a deposit plus the total monthly installments, Samatha paid $3000+$9000=$12000 for the refrigerator on higher purchase. If she would have bought the refrigerator on the cash prize, Samantha would have paid $12000- to $8000= $4000 less.

First find the weight of food Karen eats every hour: 2 pounds * 1/3 = 2/3 pounds food. Then find the total amount of weight Karen's backpack loses per hour she hikes: 2 pounds water/hour + 2/3 pound food/hour = 8/3 pounds/hour. Multiply this by the number of hours she hikes to find the total amount of weight she loses: 8/3 pounds/hour * 6 hours = 16 pounds. Add the weight of all her items to find total starting weight: 20 pounds + 10 pounds + 20 pounds = 50 pounds. Then subtract the weight she loses from the starting weight to find the weight after 6 hours: 50 pounds - 16 pounds = 34 pounds
