To calculate how many weeks Makaila will need to work before she can afford to move out, we can follow these steps:

1. Calculate Makaila's weekly income:

Makaila earns $13.25 per hour and works 40 hours per week.

$\text{Weekly income} = 13.25 \times 40 = 530 \, \text{dollars per week}$

2. Determine her weekly expenses:

Makaila pays $70 per week to help with the water bill and spends $75 per week on herself.

$\text{Total weekly expenses} = 70 + 75 = 145 \, \text{dollars per week}$

3. Calculate her weekly savings:

To find her savings per week, subtract her weekly expenses from her weekly income.

$\text{Weekly savings} = 530 - 145 = 385 \, \text{dollars per week}$

4. Determine how many weeks it will take to save $3,900:

Now, we divide her total moving out expenses by her weekly savings.

$\text{Number of weeks} = \frac{3900}{385} \approx 10.13 \, \text{weeks}$

Makaila will need to work approximately 11 weeks (rounding up to a whole number) before she can afford to move out.

Here are five related questions:

1. What is the effect of working more than 40 hours per week on her savings?
2. How would her savings change if her expenses increased?
3. What if Makaila earned $15 per hour instead—how many weeks would she need then?
4. How could budgeting reduce her weekly expenses and help her move out sooner?
5. How many weeks would it take if her move-out expenses increased to $4,500?

Tip: Keep track of your weekly income and expenses to understand how long it takes to reach financial goals!
