Question: A snack machine accepts only quarters. Candy bars cost ¢25, each piece of chocolate costs ¢75, and a pack of juice costs ¢50. How many quarters are needed to buy three candy bars, two pieces of chocolate, and one pack of juice? Think carefully first, then make a decision:
Three candy bars cost ¢25 x 3 = ¢75. Two pieces of chocolate cost ¢75 x 2 = ¢150. So, the total amount needed to buy those is ¢75 + ¢150 + ¢50 = ¢275. Since a quarter is equal to ¢25, therefore ¢275 / ¢25 = 11 quarters are needed. So the answer is 11.
