Explanation:
To find out how much money Liam will have after 5 weeks of saving, you can use the following equation:
Total money after 5 weeks = Initial amount + (Amount saved per week × Number of weeks)
In Liam's case:
Initial amount = $65
Amount saved per week = $8
Number of weeks = 5
Now, plug these values into the equation:
Total money after 5 weeks = $65 + ($8 × 5)
Total money after 5 weeks = $65 + $40
Total money after 5 weeks = $105
So, Liam will have a total of $105 after 5 weeks of saving.
Now, to write an expression that represents the amount of money Liam would have saved in w weeks, you can use the formula:
Amount saved in w weeks = Initial amount + (Amount saved per week × Number of weeks)
Using the variables:
Initial amount = $65
Amount saved per week = $8
Number of weeks = w
The expression would be:
Amount saved in w weeks = $65 + ($8 × w)
This expression can be used to calculate the amount of money Liam would have saved after any number of weeks (represented by 'w').
