Austin is comparing the prices of two truck rental companies. Company A charges $4 per hour and an additional $70 as service cha
solniwko [45]
A(h)=4h+70, A(h)=dollars to rent for h hours, h=hours rented.

B(h)=5h+60,  same variable explanations...

....

To compare the two values at 6 hours you have:

A(6)=4(6)+70=24+70=$94

B(6)=5(6)+60=30+60=$90

So at 6 hours Company B would charge $4 less than Company A

...

Savings at 7 hours of rental by using B instead of A is:

S(h)=A(h)-B(h)

S(h)=4h+70-5h-60

S(h)=-h+10

S(7)=-7+10=$3

So at 7 hours, Company B saves you $3.
