Question

A bicycle store opened and sold 11 bikes on the first month. After a few months, the store owner calculates that bike sales have been growing at a rate of 3 bikes per month since opening.

I need to write a function that relates the number of bicycles sold in a month to the number of months since the store opening.

Answer 1

Let the number of month be t. Since it is growing at a rate of 3 bikes per month, the function should involve 3t. The function is f(t) = 3t+11

Answer 2

thats what i thought

Answer 3

but if the first month he got 11
