Equations with Rational Coefficients

Question

Simone saved $65.35 more than her brother Dan and $37.50 less than her sister Carly. Carly saved 127.75. Write and solve equations to find how much money Simone and Dan saved.

Answer 1

S=65.35 + D

S= C -37.50

C= $127.75

S= 127.75-37.50 = $90.25

D = 90.25 - 65.35 = $24.90
