Step-by-step explanation:
Let, Jamie needs "$ g" for the trip. Then, according to the question,
g = 600 -------------------(1)
Let, Stella needs "$ m" for the trip. Then, according to the question,
m = 600 -------------(2)
if Jamie washes x no. of cars for $25 each and Stella makes y no. of pies
for $ 15 each, then, according to the question,
25x ≥ 600 ≥ 15y -------------(3)
