SCORPION-xisa [38]
So, to figure out this problem you first need to solve for how much you have left after paying the base fee. Take the total ($84) and subtract by the base fee ($27). You will get 57 as your answer. Then, take $57 and divide it by $0.15 to get your answer. It is 380 minutes each month. The equation here is 84=27+0.15x.

I will give brainliest to anyone who gives me a correct answer
Pachacha [2.7K]

Answer:

C

Step-by-step explanation:

Let's check the first condition [y=110, t=0] for all the choices and eliminate:

A)

y = 110e^{7t} - 80\\y = 110e^{0} - 80\\y=30

NO

B)

y = 110 - 80e^{-5t}\\y = 110 - 80e^{0}\\y=30

NO

C)

y = 30 + 80e^{-2t}\\y = 30 + 80e^{0}\\y=110

YES

D)

y = 110 - 80e^{2t}\\y = 110 - 80e^{0}\\y=30

NO

E)

y = 30 - 80e^{-4t}\\y = 30 - 80e^{0}\\y=-50

NO

Note: e^0 = 1

Only C is satisfied. But let's make sure the 2nd condition applies as well.

y = 30 + 80e^{-2t}\\y = 30 + 80e^{-\infty}\\y=30+\frac{80}{e^{\infty}}\\y>>30

Hence, y approaches 30 as t goes to infinity. 2nd condition is satisfied as well.

Answer is C
