Problema Solution
a parking meter contains nickels and dimes worth $4.60. there are 53 coins in all. how many of each are there?
Answer provided by our tutors
1 nickel = 5 cents = $0.05
1 dime = 10 cents = $0.1
let
n = the number of nickels
d = the number of dimes
a parking meter contains nickels and dimes worth $4.60
0.05n + 0.1d = 4.60
there are 53 coins in all
n + d = 53
by solving the system of equations
0.05n + 0.1d = 4.60
n + d = 53
we find
n = 14 nickles
d = 39 dimes
