Sagot :

28.50÷3= 9.50/ hr


2 hours would be
2×9.50= $19


4.5 hours would be
4.5×9.5=42.75

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
