Question

Exponential models question!

Answer 1

so i know that y=ab^x. To solve this equation i need to find B by adding r+1. Does that make B .125 or is it .0125?

Answer 2

my bad, would it be 1.0125 or 1.125?

Answer 3

@dtan5457 can you explain this to me? why it would be one or the other?^

Answer 4

12.5% = 12.5/100 = 0.125

so r = 0.125

Answer 5

1+r = 1+0.125 = 1.125

Answer 6

okay, so then 1.125^30= 34.25

Answer 7
