Answer: C) 6 minutes.

Step-by-step explanation: to solve the given problem we can replace the given option in the values of x, and calculate y for each option, the one that results in y=1080 feet will be the correct answer:

for option A:

y=4^{5}-6*4^{4}+3 *4^{3}-18*4^{2}  +180*4

y=1024-1536+192-288+720

y=112 feet.

for option B:

y=5^{5}-6*5^{4}+3 *5^{3}-18*5^{2}  +180*5

y=3125-3750+375-450+900

y=200 feet.

for option C:

y=6^{5}-6*6^{4}+3 *6^{3}-18*6^{2}  +180*6

y=7776-7776+648-648+1080

y=1080 feet. As we can see the ballon will reach an elevation of 1080 feet in 6 minutes.
