Answer:
(x - 8)(x + 2) = 0
Step-by-step explanation:
To rewrite the equation, we need to factor:
x² - 6x - 16 = 0
(x - 8)(x + 2) = 0
The total cost will be $56 because 3 x 8 = 24 so then you multiply 7 x 8 = 56.
90 + (5x-1) + 8x = 180
90 + 5x - 1 + 8x = 180
89 + 5x + 8x = 180
89 + 13x = 180
13x = 91
x = 7
