Heather works as a tutor for 7 an hour and as a waitress for 14 an hour. This month, she worked a combined total of 95 hours at her two jobs.
Let be the number of hours Heather worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month
7x + 14(95-x)
To calculate the combined amount Heather earned this month, we need to consider her hourly wage as a tutor and as a waitress, as well as the number of hours worked for each job.
Let's assume that Heather worked "x" hours as a tutor this month.
Heather's wage as a tutor is $7 per hour. So, the total amount she earned as a tutor is 7 multiplied by the number of hours worked as a tutor, which is 7x.
Heather's wage as a waitress is $14 per hour. The remaining hours will be her hours as a waitress, which is the difference between the total hours worked (95 hours) and the hours worked as a tutor (x). Therefore, her hours as a waitress will be (95 - x).
So, the total amount Heather earned this month is the sum of the amount earned as a tutor and the amount earned as a waitress:
Total earnings = (Amount earned as a tutor) + (Amount earned as a waitress)
Total earnings = 7x + (14 * (95 - x))
Therefore, the expression for the combined total dollar amount Heather earned this month is 7x + (14 * (95 - x)).
