The rest stop snack machines accept quarters only. You are making snack purchases for people traveling with you. You need to buy 2 candy bars, a pack of peanuts, and one can of soda. A sign on the machines tells you the prices: candy bars cost 0.25 cents, a bag of peanuts costs 0.50 cents, and a can of soda costs 0.75 cents. There is a change machine in the lobby area. How many quarters will you need to make the required purchases?



All together you will need \(\$1.75\) to make the required purchases, or 7 quarters.
