Terry has 2 more quarters than fines and has a total of $6.80. how many quarters and dimes does terry have?

Terry has 20 quarters and 18 dimes

Step-by-step explanation:

Let

x > the number of quarters

y > the number of dimes

Remember that

1 quarter=$0.25

1 dime=$0.10

we know that

x=y+2 > equation A

0.25x+0.10y=6.80 > equation B

Substitute equation A in equation B and solve for y

0.25(y+2)+0.10y=6.80

0.25y+0.50+0.10y=6.80

0.25y+0.10y=6.80-0.50

0.35y=6.30

y=18 dimes

Find the value of x

x=y+2 > x=18+2=20 quarters

therefore

Terry has 20 quarters and 18 dimes
