Answer:
He need 202.5
Step-by-step explanation:
F(x)= 8.50(35) f(x)= 297.5 500-297.5 = 202.5
because he work 8.50dollar an hour and he work 35 hour. So, you multiply it, 8.5(35) = 297.5 and a PS5 cost 500 dollar but you only have 297.5 dollar. So, you subtract and you will get 202.5 dollar need for a PS5.
