A customer's bill for maintenance and repair at a service station showed 6 quarts of oil at $1.15 each an air filter at $3.75 an oil filter at $7.45 13 gallons of gasoline at $1.15 a gallon and 3 hours labor at $37.00 an hour What was the total bill?

And your answer is?

Make an equation out of it:

y = the total cost of the bill.

y = (6 x $1.15) + $3.75 + $7.45 + (13 x $1.15) + (3 x $37.00)

Do the math and you'll have your answer.

The answer is 144.05

That is correct!

To calculate the total bill for maintenance and repair at the service station, we need to add up the costs of the oil, air filter, oil filter, gasoline, and labor.

Let's break down the costs:
- Six quarts of oil at $1.15 each: 6 x $1.15 = $6.90
- One air filter at $3.75
- One oil filter at $7.45
- Thirteen gallons of gasoline at $1.15 per gallon: 13 x $1.15 = $14.95
- Three hours of labor at $37.00 per hour: 3 x $37.00 = $111.00

Now, let's add up all the costs:
$6.90 (oil) + $3.75 (air filter) + $7.45 (oil filter) + $14.95 (gasoline) + $111.00 (labor) = $144.05

Therefore, the total bill for the maintenance and repair at the service station is $144.05.
