Eloise needs to rent a car. She goes to the rental agency and finds out that she will have to pay a fee of $35 and then an additional $0.10 for every mile that she drives. How much will she have to pay if she drives 20 miles?
Well, $35 dollars no matter how many miles. if she drove 20 miles, we will say that x represents miles driven. So, the cost will be $35 + $0.10x to solve, substitute 20 for x. $35 + $0.10(20) $35 + $2 $37
