Answer the question

Answer 1

40

450

Explanation:

The amount of money added per week is 40 dollars because the function tells us for every increase in x by 1, y increases by 40.

The starting amount of money in the account is when x (the number of weeks before Debra has been adding money) = 0. When x = 0, the function gives

`\begin{gathered} y=40(0)+450 \\ y=450 \end{gathered}`

Hence, the starting amount of money in the account in $450.
