[Question]: Milo's parents tell him that he can win cash rewards for good grades. He will get $5 times the average grade he gets. He gets three 2s, four 3s, a 4, and a 5. How much cash does he get?
[Answer]: His total score is 27 because (3 x 2) + (4 x 3) + 4 + 5 = 27. His total number of grades is 9 because 3 + 4 + 1 + 1 = 9. His average grade is a 3 because 27 / 9 = 3. He earns $15 because 5 x 3 = 15.
So the answer is 15.

[Question]: 25% of oysters have pearls in them. Jamie can collect 16 oysters during each dive. How many dives does he have to make to collect 56 pearls?
[Answer]: First find how many pearls Jamie collects per dive by multiplying the number of oysters by the chance each oyster has a pearl: .25 pearls / oyster * 16 oysters / dive = 4 pearls / dive. Then divide the number of pearls he wants by the number of pearls per dive to find the number of dives: 56 pearls / 4 pearls / dive = 14 pearls / dive.
So the answer is 14.

[Question]: Cappuccinos cost $2, iced teas cost $3, cafe lattes cost $1.5 and espressos cost $1 each. Sandy orders some drinks for herself and some friends. She orders three cappuccinos, two iced teas, two cafe lattes, and two espressos. How much change does she receive back for a twenty-dollar bill?
[Answer]:
Find the total cost of the cappuccinos by multiplying the price by the quantity: 3 cappuccinos x $2 / cappuccino = $6. Then do the same for the iced teas: 2 iced teas x $3 / tea = $6. Then do the same for the cafe lattes: 2 lattes x $1.5 / latte = $3. Then do the same for the espressos: 2 espressos x $1 = $2. In total Sandy pays $6 + $6 + $3 + $2 = $17. Sandy will receive $20 - $17 = $3 in change.
So the answer is 3.
