Problema Solution
Edgar has 20 dimes and nickels, which together total $1.40. How many of each does he have?
Answer provided by our tutors
1 nickle = 5 cents
1 dime = 10 cents
let
n = the number of nickles
d = the number of dimes
Edgar has 20 dimes and nickels, which together total $1.40 = 140 cents
n + d = 20
5n + 10d = 140
by solving the system of equations we find
n = 12 nickles
d = 8 dimes
