Q: Randy got 90, 98, 92, and 94 in his first four quizzes. His goal is to get a 94 average on his 5 quizzes. What score should he get in the fifth quiz to reach his desired average?
A: Since Randy wants to get an average of 94, then the sum of the 5 quizzes should be 94 x 5 = 470. The sum of Randy's score for the first four quizzes is 90 + 98 + 92 + 94 = 374. Thus, Randy needs to get 470 - 374 = 96 in his fifth quiz. The answer is 96.

Q: Brian is taping up some boxes. Each box needs three pieces of tape, one as long as the long side and two as long as the short side. If Brian tapes up 5 boxes that measure 15 inches by 30 inches and 2 boxes that measure 40 inches square, how much tape does he need?
A: First find the amount of tape each 15 in x 30 in box needs on the short sides: 2 sides * 15 inches / side = 30 inches. Then add that to the amount of tape each 15 in x 30 in box needs on the long side to find the total amount needed per box: 30 inches + 30 inches = 60 inches. Then multiply that amount by 5 boxes to find the total amount needed: 60 inches / box * 5 boxes = 300 inches. Then find the amount of tape each 40 in x 40 in box needs for its three equal length sides: 3 sides * 40 inches / side = 120 inches. Then multiply that amount by 2 boxes to find the total amount needed: 120 inches / box * 2 boxes = 240 inches. Then add the total amount needed for each box size to find the grand total: 240 inches + 300 inches = 540 inches. The answer is 540.

Q: There were 15 males and 10 more girls at the party. Each attendee received 2 cans of soft drinks. If Mary bought several boxes of soft drinks where a box contains 8 cans and is priced at $5 for each box, how much did Mary spend on soft drinks?
A:
There were 10 + 15 = 25 girls in the party. So, there were a total of 15 + 25 = 40 attendees. 40 x 2 = 80 cans of soft drinks are needed. So, Mary bought 80 / 8 = 10 boxes of soft drinks. Therefore, Mary spent 10 x $5 = $50 on soft drinks. The answer is 50.
