Question

nicole works as a tutor for an hour and as a waitress for an hour. this month, she worked a combined total of hours at her two jobs. let be the number of hours nicole worked as a tutor this month. write an expression for the combined total dollar amount she earned this month.

Answer 1

The expression for Nicole's combined total dollar amount earned this month is (Rate per hour as a tutor) * x + (Rate per hour as a waitress) * (Total hours - x)

Step-by-step explanation:

The combined total dollar amount Nicole earned this month can be calculated by multiplying the number of hours she worked as a tutor by the rate she earns per hour as a tutor, and then adding the product to the product of the number of hours she worked as a waitress and her rate per hour as a waitress. The expression for the combined total dollar amount she earned this month is given by:

Total earnings = (Rate per hour as a tutor) * (Number of hours as a tutor) + (Rate per hour as a waitress) * (Number of hours as a waitress)

In this case, the number of hours Nicole worked as a tutor is represented by the letter 'x', so the expression becomes:

Total earnings = (Rate per hour as a tutor) * x + (Rate per hour as a waitress) * (Total hours - x)
