Question

Ana has $75 and saves an additional $13 per week. Which equation can be used to findhow many weeks it will take until she has $452?75 + w = 4520 75 + 13w = 45213w = 75 = 452452 + 13w = 75

Answer 1

`\begin{gathered} \text{The equation is;} \\ 75\text{ + 13w = 452} \end{gathered}`

Here, we want to get an equation

Firstly, since we do not have the number of weeks, we can represent it with a variable (a letter)

In this case, we shall be representing it with w

Since she saves $13 in a week, in w weeks, the amount saved will be;

13 * w = $13w

Now, recall that she has $75 before she started saving. What this mean is that at the end of the w weeks, the amount she will have will be ;

`13w\text{ + 75}`

We now proceed to equate this to the total she wants to save and we finally have the complete equation below;

`13w\text{ + 75 = 452}`
