Question

Issa rents a car for a work trip. The rental fee is $200 in total. She also decides to purchase the insurance, which is $18 per day.

Select the expression that will help her determine what the total cost to the company will be.

Answer 1

Solution: To determine the total cost to the company for Issa's car rental, we need to consider both the rental fee and the insurance cost. Since the insurance cost is given as a daily rate, we need to determine the number of days Issa will be renting the car.

Let's assume Issa will be renting the car for "d" days.

Expression for Total cost = Rental fee + (Insurance cost per day * Number of days)

Total cost = $200 + ($18 * d)

Therefore, the expression that will help determine the total cost to the company is $200 + ($18 * d).

Answer 2

Hi Ginger,

Since we are told the total rental fee (without insurance) is $200, we know the cost for Issa's rental is at least $200.

Then we are told that Issa wants to add the insurance, which costs $18/day. But we don't know how many days Issa's trip is for, so we should use "x" to represent the number of days. So Issa's insurance cost for the trip is $18/day * x days = 18x dollars

Therefore, Issa's total rental will cost 200 + 18x (in units of dollars).

I hope this helps!
