Christy will have to work 50 hours to pay off her debt.
500 divided by 10 = 50.
Hope this helped!
<span>dA/dx = 100 - 4x & the 2nd derivative is -4 [i.e. -ve]
so setting dA/dx to zero will give a maxima
100 - 4x = 0
so x = 25 m
in other words, a rectangle with a given perimeter has the maximum area when it is a square</span>

Answer:
-5(y - 3)/-2
Step-by-step explanation:
y² - 9/-2y × -5y/y + 3
Multiply Rewrite
Simplify the expression
(y - 3)×(y + 3)/2 × 5/y + 3
Simplify the expression
y - 3/2 × 5
Calculate
5(y - 3)/2
HOPE THIS HELPS :)
