Problema Solution
Susan has $2.35 in nickels and dimes. If she has 33 coins in all, find the number of nickels and dimes.
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
Susan has $2.35 in nickels and dimes
0.05n + 0.1*d = 2.35
she has 33 coins in all
n + d = 33
by solving the system of equations
n + d = 33
0.05n + 0.1*d = 2.35
we find
d = 14 nickles
n = 19 dimes
