Question

The total number of sales of a cookbook is modeled by the function () =10,587(1.024)^. If the initial total number of sales (that is, the total number of saleswhen = 0) was measured January 1, 2014, what was the initial total number ofsales?

Answer 1

Given:

`\mleft(\mright)=10587(1.024)^x`

To find the initial number of sales:

Substituting x=0 we get,

`\begin{gathered} f(0)=10587(1.024)^0 \\ =10587(1) \\ =10587 \end{gathered}`

Thus, the initial number of sales is 10587.
