Nicole wants to buy a pair of jeans. the original cost of the jeans is $42.50 and he markup is 10 percent. how much will she have to pay for the jeans ?

She'll have to pay $46.75

Step-by-step explanation:

42.50 divided by 10% is 425 which equals $4.25. 42.50 + 4.25 = 46.75

42.50 + 10% = 46.75. So therefore you can check your answer twice and it will be the same answer.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
