Answer:
$76.80
Step-by-step explanation:
When a product has a certain markup, you need to multiply the markup by the price of the product, and then add that to the original price of the product. 20%=0.2, and 0.2*64=12.8. Adding this to the original price, you get 64+12.8=$76.80. Hope this helps!
2(x+1)(x- 6) this is probably correct
9+-3 means 9 plus 3 less
basically it is 9-3=6
22+26+28+30+39+44+62+63= 314
Divide the answer by the amount of numbers
=39.25
