Question

Janelle has 342 pennies , 62 nickels,and 12 dimes. If Janelle exchanges her coins for dollars, how many dollars will she have? How much cent will remain

Answer 1

Well first, you gotta change all of them into pennies so it would be easier. 342 pennies = 342 pennies, 62 nickels = 310 pennies, and 12 dimes = 120 pennies. Then you add them up: 342 + 310 + 120 = 772. You move the decimal two places to the left. 772 = 7.72. The answer will be 7 dollars, 72 cents remain.
