Problema Solution
you have $6.10 in nickles and quarters. you have 62 coins. how many of each do you have?
Answer provided by our tutors
1 nickle = 5 cents
1 quarter = 25 cents
let
n = the number of nickels
q = the number of quarters
you have $6.10 = 610 cents in nickles and quarters
5n + 25q = 610 divide both sides by 5
n + 5q = 122
you have 62 coins
n + q = 62
by solving the system of equations
n + 5q = 122
n + q = 62
we find
n = 47 nickles
q = 15 quarters
