Question

Sam has five more dimes and quarters and four fewer nickels than quarters if she has a total of 4.70 how many of each does she have

Answer 1

X is unknown

Quarters 25x

Dimes 10(x+5)

Nickes 5 (x-4)

Solve for x first

25x + 10(x+5) + 5(x-4) = 470

40x + 50 - 20 = 470

40x = 440

x = 11, number of quarters
