Aliya Patton · Answer 1

y = 240000 x e^ (0.078 x t)

Step-by-step explanation:

This is exponential growth, so the power at the exponential function will be positive (negative is for exponential decay.) Since it is increasing by 7.8 percent exponentially we can write an exponential function relating y with t.
