Question

Hi! I need a bit of help to understand this please.

Answer 1

Given the following question:

`\begin{gathered} S=450+30w \\ S\text{ representing the total amount of money} \\ w\text{ representing weks each wek she adds 30} \\ 450\text{ representing the orginal amount she added but since it's first it goes before 30} \end{gathered}`

Now for part two:

Find the amount of money after 17 weeks

`\begin{gathered} S=450+30w \\ w=17 \\ S=450+30(17) \\ 30*17=510 \\ S=450+510 \\ 450+510=960 \\ S=960 \end{gathered}`

After 17 weeks she will have 960 dollars.
