I neeeeeeeeed help with a math problem.

Question

Keiko works as a tutor for $14 an hour and as a waitress for $11 an hour. This month, she worked a combined total of 91 hours at her two jobs.Let t be the number of hours Keiko worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month. Then solve the equation.

Please, and thank you :)

Answer 1

Not sure that this can be fully flushed out and solved because the total amount has to remain a variable since the total is unknown. Expressions can be written out for each job but there are too many extra variables in each expression to fully solve it. More information would be needed.

What we can do:

Between both jobs, she worked 91 hours. Let tutor equal t and waitress equal w:

t + w = 91

To get hours for tutor:

t = 91 - w

To get hours for waitress:

w = 91 - t

The expression for calculating total dollar amount is:

14t + 11w = total

Hope this helps!

Answer 2

Total amount A = Tx14 + Wx11

T. hours as tutor

W hours as waiter, W=91-T

A = T x14 + (91-T)11

A = 14T - 11T + 91x11

A = 3T + 1001

If you know how much Keiko made (A), you could find T and then W.
