Answer:
8 dimes, 15 quarters
Explanation:
The number of dimes=x
The number of quarters=x+7
So the value of each dime and quarter is 0.10 and 0.25
0.1x+0.25(x+7)=4.55
0.1x+0.25x+1.75=4.55
0.35x+1.75=4.55
0.35x+1.75–1.75=4.55–1.75
0.35x=2.8
0.35x/0.35=2.8/0.35
x=8
So the number of dimes there are is 8.
The number of quarters:
x+7
=8+7
=15
So, the number of dimes and quarters in this order are: 8 and 15.
