Question

Milanputting money into a savings account. He starts with $350 in the savings account, and each week he adds $60.Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Milan has been adding money. Write anequation relating S to W. Then use this equation to find the total amount of money in the savings account after 17 weeks.

Answer 1

We know that he starts with $650 in the savings account, and each week he adds $30.

If S represents the total amount of money and w the number of weeks, an equation that realtes S to w is compounded by:

1. An constant value that is the value which he starts

S = 650

2. Multiplying the number of weeks by the money he adds weekly

S = 650 + w30

So, the equation that relates S to w is

`S=650+w30`

Now, we must calculate the total amount of money after 19 weeks.

In order to calculate this value we must replace w = 19 in the equaton

`\begin{gathered} S=650+(19)(30) \\ S=1220 \end{gathered}`

So, after 17 weeks there are $1220
