Problema Solution
Jo has 62 coins only of nickels and dimes. The value of his coins is 4.50. Carson has _ nickels and _ dimes
Answer provided by our tutors
we assume that "Carson" is the same person as "Jo"
let 'x' represent the number of nickels, then '62-x' represents the number of dimes
4.50 = 0.05x + 0.10(62-x)
solving for 'x' we have x=34
62-34 = 28
Jo has 34 nickels and 28 dimes [and presumably so does Carson]
