Question

Mr. Martinez has 750 boxes of cookies in his store, and each week he plans to sell 150 boxes of cookies.Assuming he does not receive a new shipment of cookies, how many boxes of cookies does he expect tohave in his store at the end of w weeks, where w is an integer and 1

Answer 1

Let:

b = initial amount of boxes

a = sold boxes per week

w = Number of weeks

T = total number of boxes in his store

so:

`\begin{gathered} T=b-ax \\ so\colon \\ T=750-150w \end{gathered}`
