Answer:

Total earned(in dollars) [tex]=2\ t+920[/tex]

Step-by-step explanation:

Given:

Michael's hourly rate working as a tutor = $12 per hour

Michael's hourly rate working as a waiter = $10 per hour

Total number of hours worked by Michael for both jobs this month = 92

Let the number of hours Michael works as a tutor this month be [tex]=t[/tex] hours.

∴ Number of hours Michael works as a waiter this month will be [tex]=(92-t)[/tex] hours.

Amount earned by Michael this month from tutor job

⇒[tex]\textrm{Hourly rate}\times\textrm{Number of hours worked}[/tex]

⇒[tex]12\times t[/tex]

⇒[tex]\$12\ t[/tex]

Amount earned by Michael this month from tutor job

⇒ [tex]\textrm{Hourly rate}\times\textrm{Number of hours worked}[/tex]

⇒[tex]10\times (92-t)[/tex]    

⇒[tex]\$(920-10\ t)[/tex]     [Using distribution]

Total amount earned by Michael from both the jobs this month in dollars can be given as

⇒[tex]\textrm{Amount earned from tutor job+Amount earned from waiter job}[/tex]

⇒[tex] 12\ t+(920-10\ t)[/tex]

⇒[tex]12\ t+920-10\ t[/tex]

⇒[tex]2\ t+920[/tex]
