Answer:
13 Quarters
Step-by-step explanation:
Let <u>D</u> and <u>Q</u> stand for the numbers of Dimes and Quarters.
We are told that:
D + Q = 31
We also find that:
D = Q + 5
Use the second expression (for D) in place of D in the first equation:
D + Q = 31
(Q+5) + Q = 31
2Q = 26
<u>Q = 13</u>
This means there are:
D = 13 + 5 or <u>18 Dimes</u>
======================
Check
D + Q = 31 ?
18 + 13 = 31 <u> YES</u>
D = Q + 5 ?
18 = 13 + 5 <u>YES</u>
I think it is B. Hope this helps!
