Answer:

(x-10)(x+10)

Step-by-step explanation:

x^2 – 100

This is the difference of squares

x^2 - 10^2

We know that (a^2 - b^2) = (a-b) (a+b)

(x-10)(x+10)

He needs to purchase some work clothes and notices that J.C. Penney is having a 25% off of your total purchase sale. He decides
SVETLANKA909090 [29]
First, lets determine the regular price of his purchase :

16.99 (3) + 34.99 (3) + 52.99 (2) + 5.99 (5) = 50.97 + 104.97 + 105.98 + 29.95 = 291.87

Therefore, the regular price of his purchase is $291.87 before sales tax.

If he receives 25% off of his total purchase, then the price is now :

291.87 * .75 = $218.90

We multiply by 75% because we are only paying 75% of the total purchase price since we received a 25% discount.

The total savings is 

291.87 - 218.90 = $72.97

If sales tax is 10%, the total purchase price after sales tax is :

218.90 * 1.10 = $240.79

The sales tax is $21.89 since

240.79 -218.90 = 21.89

If he pays with 3 $100 bills, we should receive :

300 - 240.79 = $59.21 

in change.
