Problema Solution
George saves nickels and dimes for tolls on the New Jersey turnpike. If he has 28 coins that are worth $2.60, how many are nickels amd how many are dimes?
Answer provided by our tutors
1 nickle = 5 cents
1 dime = 10 cents
$2.60 = 250 cents
let
n = the number of nickles, n>0
d = the number of dimes, d>0
he has 28 coins that are worth $2.60:
n + d = 28
5n + 10d = 260
by solving the above system of equations we find:
n = 4 nickles
d = 24 dimes
