Question

Debra works as a tutor and as a waitress for $11 an hour. THIS MONTH, she worked a combined total of 97 hours at her two jobs. Let t be the number of hours Debra worked as a tutor this month. WRITE AN EXPRESSION FOR THE COMBINED TOTAL DOLLAR AMOUNT SHE EARNED THIS MONTH.

Answer 1

(x -11) * t + 1067

Explanation:

We know that in her tutoring job she earns x amount of money and how waitress earns $ 11 / hour.

They give us the combined number of hours that he works with all the jobs, which is 97, but from here we can say that in the time that he does NOT work as a tutor it is actually 97 - t.

Total earned this month = x * t + 11 * (97 -t)

Total earned this month = x * t + 1067 - 11 * t = (x -11) * t + 1067
