Answer:
$9 or 9% less
Step-by-step explanation:
Original Price = OP
$75= OP
75 x .2 (20% discount) = 15
$15 discount
$75 - $15 = $60
$60 x .1 (service fee) = 6
$60 + $6= $66
Op ($75) - $66 = 9
$9 less than OP
How I check the percentage (probaly not how ur supposed to but ah well)
75 = 100%
75 + 25 = 100 but 25 more than 100%
66 + 25 = 91, also makes 75 100% again
100%-91%=9%
X=4
You have to distribute the negative sign for everything in the parentheses. After that you add x to the other side then add 8 to the opposite side to move them. Then your answer is 4.
so you have your two equations 3x+7=5x-23 and solve for x which is your "number" leaving the answer to be <u>x=15</u>
