Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year. Which function equation represents the value of the bicycle after t years? f(t)=478(0.935)^t
f(t)=478(0.065)^t
f(t)=478(6.5)^t
f(t)=478(1.065)^t

Answer:

Correct choice is A

Explanation:

Note that 6.5% is 0.065 as decimal.

Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year, then the function that represents the situation is


y=478\cdot (1-0.065)^t=478\cdot (0.935)^t,

where t is time (in years).

Options C and D are false, because functions are increasing, option B is false, because this function represents how much will the value decrease.
