Question

It costs $45 to rent a car each day. There is also a fee of $12. How much does it cost to rent a car for 5 days,including the fee? Write an equation for each problem. Use a variable for the unknown. Solve.

Answer 1

The equation is 12 + (45n) n is number of days.

$12 + ($45*5)= $12 + $225= $237

Answer 2

An equation for each problem is
`y = 12+45x`

The total cost for 5 days is $237

Explanation:

Rent per day of car = $45

Let x be the no. of days

Rent for x days = 45x

There is also a fee of $12

So, Total cost for x days = 12+45x

Let y denotes the total cost

An equation for each problem is
`y = 12+45x`

Substitute x = 5

`y = 12+45(5)`

`y = 237`

Hence the total cost for 5 days is $237
