If Rachael has 3 more dimes than quarters and they have a combined value of 275 cents, how many of each coin does she have?
Answer provided by our tutors
1 dime = 10 cents
1 quarter = 25 cents
let
d = the number of dimes, d>0, d is integer
q = the number of quarters, q>0, q is integer
Rachael has 3 more dimes than quarters and they have a combined value of 275 cents:
d = 3 + q
10d + 25q = 275
by solving the above system of equations we find:
d = 10 dimes
q = 7 quarters
