Suppose you earn $7.21 per hour and plan to work "h" hours per week. write an expression using variables that models the amount of money you will earn each week.

Then, suppose you earn $10 in tips per week, regardless of the hours you work. How does this change the equation

If you earn $7.21 per hour and work 8 hours a week. How much do you earn?

If you earn $7.21 per hour and work h hours a week. How much do you earn?

Since the tips of $10 per week is independent of the number of hours worked, simply add $10 to the weekly pay.

To write an expression that models the amount of money you will earn each week based on the number of hours worked, you can multiply your hourly wage ($7.21) by the number of hours worked "h". This can be represented as:

Earnings = $7.21/hour * h

Simplifying this expression, you get:

Earnings = 7.21h

Now, to incorporate the additional $10 you earn in tips per week regardless of the hours worked, you would need to add this amount to the earnings expressed above. So the new expression becomes:

Earnings = 7.21h + $10

This equation represents the total amount of money you will earn each week, considering both your hourly wage and the additional tips.
