Question

John went on vacation. He rented a car for a flat rate of $50 and the

cost per day was $27.50. The total cost for John rental car was
$242.50. How many days did John rent the car?

Answer 1

John rented the car for 7 days. This was determined by setting up a linear equation with the total cost of $242.50, subtracting the flat rate of $50, and dividing the remainder by the daily rate of $27.50.

Step-by-step explanation:

To determine how many days John rented the car, we first need to consider the flat rate and daily charge. According to the problem, John paid a flat rate of $50 and a daily rate of $27.50. The total cost of the car rental was $242.50. We can set up a linear equation to find the number of days John rented the car.

Let d represent the number of rental days. The total cost (T) of renting the car can be calculated using the following formula:

T = flat rate + (daily rate × number of days)

Which translates to:

T = $50 + $27.50d

Since the total cost is $242.50, we can substitute T with 242.50 and solve for d:

242.50 = $50 + $27.50d

To solve for d, we first subtract the flat rate from the total cost:

242.50 - $50 = $27.50d

Which simplifies to:

192.50 = $27.50d

Now, we divide both sides by the daily rate to find the number of days:

d = 192.50 ÷ $27.50

Which gives us:

d = 7

Therefore, John rented the car for 7 days.

Answer 2

7 days because if she subtract 50 from 242.50 you have 192.50 and then u divide that by 27.50 which gets you 7 days.
