Question

7. A coin bank contains $12.45 in quarters and dimes. If there are 16 more dimes than quarters,

how many are there of each?

Answer 1

x = 40

Explanation:

We can set up the following equations to represent the problem:

x = number of quarters

x + 16 = number of dimes

0.25x + 0.1(x + 16) = 12.45

Solving for x, we get:

x = 40

So there are 40 quarters and 56 dimes in the coin bank.
