If the original price is $45 the discount is 36% and the tax is 8% what is the final cost?

The answer is $31.10. Since the discount is 36% you would be paying 64% of the price. Multiply 0.64 by 45 and you get 28.8. 28.8 times 0.08 is 2.3. Add 28.8 to 2.3 and get $31.10

Correct
$4.84

Explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84
