A television regularly costs $180, but it is on sale for 40% off. There is a 5% sales tax on the sale price. How much does the t

Anuta_ua [19.1K]

Answer:

$113.4

Step-by-step explanation:

If it is 40% off then it is 100-40 = 60% of original price.

So we do 180$ * .6 = $108 before tax.

To add on tax we do: 100 + 5 = 105% of that price.

So we do: $108 * 1.05 = $113.4 after discount and tax.
