Janae saves dimes and quarters in a jar on her dresser. Janae has 35 coins in the jar for a total of

$6.50. She has 5 more quarters than dimes. How many quarters are in the jar?

quarters are 20 in number.

Step-by-step explanation:

Let d represent dimes

Let q represent quarters

d + q = 35

q = d+5

d+d+5=35

2d=35-5

2d = 30

d = 30/2

therefore dimes = 15

Substitute d for 15 to solve for q;

q=15+5

therefore quarters are 20 in number.
