Given the following question:
[tex]\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}[/tex]
Now for part two:
Find the amount of money after 17 weeks
[tex]\begin{gathered} S=450+30w \\ w=17 \\ S=450+30(17) \\ 30\times17=510 \\ S=450+510 \\ 450+510=960 \\ S=960 \end{gathered}[/tex]
After 17 weeks she will have 960 dollars.
