Question

Anton bought a picnic cooler. His total bill, with tax, was $7. 95.

He paid 6 percent sales tax. How much did he pay for the cooler

alone without the tax?

5. Write and solve the arithmetic problem for each step.

• For the cost of the cooler, solve:

?% of cost of cooler = $7. 95

• To find the total bill in terms of the cost of the cooler :

?% of cooler price

+ 6% of cooler price (tax)

?% of cost ($7. 95)

Answer 1

• For the cost of the cooler, solve:

Let the cost of the cooler be x

Then, 100% of x = x

6% of x = 0.06x

• To find the total bill in terms of the cost of the cooler:

Total bill = cooler price + tax

= x + 0.06x

= 1.06x

• Set up an equation for the total bill in terms of $7.95:

1.06x = $7.95

• Solve for x:

x = $7.95/1.06

x = $7.50

Therefore, Anton paid $7.50 for the cooler alone without the tax.
