Trina earns $28.50 tutoring for 3 hours. write an equation relating her earings m to the number of hours h she tutors. assuming the situation is proportional, how much would trina earn turtoring for 2 hours? 4.5 hours?

Equation forms :

Step-by-step explanation:

Trina earns $28.50 tutoring for 3 hours.

So, per hour earnings of Trina are = 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.

And when h = 2 hours;

m = $19.

When h = 4.5 hours;

m = $42.75

m

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
