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.
