Q: Beth has 72 marbles of three colors. Each color has the same amount of marbles. If Beth loses 5 red, twice as many blue, and three times as many yellow ones than red ones, how many marbles does she have left?
A: Beth has 72 / 3 = 24 marbles of each color. Beth has 24 - 5 = 19 red ones left. Beth lost 5 * 2 = 10 blue ones. Beth has 24 - 10 = 14 blue ones left. Beth lost 5 * 3 = 15 yellow ones. Beth has 24 - 15 = 9 yellow ones left. She has a total of 19 + 14 + 9 = 42 marbles left. The answer is 42.
Question: Tina's classroom has the same amount of students as Maura's. Zack's classroom has half the amount of total students between Tina and Maura's classrooms. How many students are there in total between the 3 classrooms if when Zack was sick there were 22 students in his class?
Answer: If Zack's classroom had 22 students when he was absent, then the total students in his class are 22 + 1 = 23. If Tina's classroom has as many students as Maura's then T = M. If Zack's classroom has half the amount of total students between Tina and Maura's classrooms then 23 = 1 / 2 * (T + M ). 23 = 1 / 2 * (T + M). We know from above that T = M, therefore 23 = (1 / 2) * (M + M) or 23 = (1 / 2) * 2M. 23 = M. Because T = M, then T is also T = 23. Between the three classes then we have a total of T + M + Z or 23 + 23 + 23 = 69. The answer is 69.

The food is going to cost Calum a total of 10 boxes of food * $25 per box of food = $250. This leaves $330 budget - $250 spent on food = $80 to spend on disco balls. Calum can therefore afford to spend $80 remaining budget / 4 disco balls = $20 on each disco ball. The answer is 20.
