Question

There are 100 coins with a total value of $10.15. How many quarters do you have? How many dimes do you have?​

Answer 1

9514 1404 393

Answer:

• 99 dimes
• 1 quarter

Explanation:

If all 100 coins were dimes, the value would be $10.00. Each dime traded for a quarter adds $0.15 to the value.

The actual value of the coins is $10.15 -10.00 = $0.15 more than it would be for all dimes. This indicates 1 dime has been traded for a quarter.

There are 99 times and 1 quarter.
