Answer:
850.
Step-by-step explanation:
Let the number at the start be x shoes. Then:
x - 50 - 0.64(x - 50) = 288
x - 0.64x - 50 + 32 = 288
0.36x = 288 + 50 - 32
0.36x = 306
x = 306/0.36 = 850.

Answer:
C. x² + 7
Step-by-step explanation:
If f(x) = 2x² + 5 and g(x) = x² - 2, then
(f - g)(x) = f(x) - g(x)
= (2x² + 5) - (x² - 2)
= 2x² + 5 - x² + 2
= 2x² - x² + 5 + 2
= x² + 7
