The volume(v) of water is an open tank varies due to evaporation as V=x^4-50x^2+700 where V is expressed in gallons and x is the number of months elapsed. If January corresponds to x=0, what will the volume of water (in galllons) in the tank be in June A. 700
B. 1200
C. 75
D. 100

step-by-step explanation:

if you want to solve percent error follow these steps.
