Question

Gary saved dimes and nickels at a ratio of 5:7. Then, he saved 20% more dimes and 3 times the number of nickels. If he had 540 dimes and nickels altogether in the end, how many more nickels then dimes did he have?

Answer 1

Explanation:

Gary saved dimes and nickels at a ratio of 5:7.

5/12 = Dimes

7/12 = Nickels

Then, he saved 20% more dimes and 3 times the number of nickels.

If he had 540 dimes and nickels altogether in the end, how many more nickels then dimes did he have?

Let the number of dimes = x

Let the number of nickels = y

Total number of dimes and nickels = 540
