Answer:
Equation forms : [tex]m=9.5h[/tex]
Step-by-step explanation:
Trina earns $28.50 tutoring for 3 hours.
So, per hour earnings of Trina are = [tex]\frac{28.50}{3}= 9.5[/tex] dollars
Let her total earnings be m
Let the number of hours she tutors be h
To establish an equation multiply the hourly rate by h.
[tex]m=9.5h[/tex]
And when h = 2 hours;
[tex]m=9.5(2)[/tex]
m = $19.
When h = 4.5 hours;
[tex]m=9.5(4.5)[/tex]
m = $42.75
