Answer 1

Given -

He rented a tile saw for = 5 days.

He rented a floor sander for = 2 days

The total cost of the rentals was = $370

To Find -

How much did it cost to rent the floor sander for 2 days?

Step-by-Step Explanation -

Let the cost of renting a tile saw for one day = $x

So, the cost of renting a floor sander for one day = $x + $10

Now,

He rented a tile saw for 5 days.

So, cost of rent = 5($x) = $5x

He rented a floor sander for 2 days

So, the cost of rent = 2($x + $10) = $2x + $20

Now, according to the question:

Total Cost = $370

So,

$5x + $2x + $20 = $370

$7x = $350

$x = 350/7

$x = 50

So,

The cost of renting a floor sander for two day = $2x + $20

= $2(50) + $20

= $100 + $20

= $120

Final Answer -

The cost to rent the floor sander for 2 days =
