Answer 1

3/4x times 7/10(3/4x)

Explanation:

We dont know the price so lets say its x.

25% off means 1/4 off, so the price is 3/4x

If the slaes tax is 7%of ^, we know that the sales tax is 3/4x times 7/10(3/4x) because 7 percent is 7/10

Answer 2

b) 25/100 x 79

= 19.75

= 79 - 19.75

= $59.25 (before tax)

7/100 x 59.25

= 414.75/100

= 4.15

= 59.25 + 4.15

= $63.4 (after adding tax)

First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.
