Problema Solution
Dannon has $10.80 in dimes and quarters. If Dannon has 32 more quarters than dimes, how many dimes does he have?
Answer provided by our tutors
1 quarter= 25 cents
1 dime = 10 cents
let
q = the number of nickels
d = the number of dimes
Dannon has $10.80 = 1080 cents in dimes and quarters
10d + 25q = 1080
Dannon has 32 more quarters than dimes
q = d + 32
by solving the system of equations
10d + 25q = 1080
q = d + 32
we find
d = 8 dimes
q = 40 quarters
