Answer:
She had 4 of each coin
Step-by-step explanation:
The values of dimes, quarters, and nickels are 10 cents, 25 cents, and 5 cents, respectively.
Since we have the same number of each coin, we can set up the equation:
[tex]0.10C + 0.25C + 0.05C = 1.60[/tex]
We can multiply both sides by 100 for simplicity
[tex]10C + 25C + 5C = 160\\40C = 160\\C = 4[/tex]
She had 4 of each.
Check:
0.10(4) + 0.25(4) + 0.05(4) =
.40 + 1 + .2 =
1.6
It checks out
