A weather balloon is launched from a height of 475 feet above sea level. If the balloon rises at a constant rate of 85 feet per minute, which equation could be used to determine t, the time in minutes it will take the balloon to reach a height of 9245 feet above sea level?

A 9245 = 85 + 475t
B 9245 = 85(t + 475)
C 9245 = 475 + 85t
D 9245 = (475 + 85)t

thank you for providing the answer choices

the 475 is a constant (does not depend on time) but the 85 feet per minute rate does

so to find the total distance we multiply 85 * the time variable, then add 475

which answer choice best captures this idea? be careful w/ order of operations
