Question

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

Answer 1

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.
