Problema Solution
Antonio has $6.75 in nickels and dimes. If Antonio 15 more dimes than nickels, how many nickels does he have?
Answer provided by our tutors
1 nickle = 5 cents
1 dime = 10 cents
let
n = the number of nickels
d = the number of dimes
Antonio has $6.75 = 675 cents in nickels and dimes
5n + 10d = 675
Antonio has 15 more dimes than nickels
d = n + 15
by solving the system of equations
5n + 10d = 675
d = n + 15
we find
n = 35 nickles
d = 50 dimes
