let the number of mugs be x
so cost of each mug is 48/x.
cost of mug for selling = 48/x +3.(three more)
total number of mugs sold = x-2.
total profit= 48 + 22 = 70.00
Equation:
Expand:
Multply the whole equation by x to remove the fraction adn simplify:
48x-96+3x^2-6x=70x
3x^2-28x-96=0
Factor:
(x-12)(3x+8)
x=12
