The product of two integers is 72.one number is two less than 5 times the other

x*y=72

x = 5y-2

x=72/y

72/y=5y-2

72=5y^2-2y

5y^2 -2y - 72 = 0

(5y+18)(y-4)=0

y = -18/5 discard

or y = 4

4x=72

x=18

(18,4)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+8

16

retail price is $16.
