Answer 29

Here is the question:
When Tiya works for h hours, how much does Tiya earn?
Follow the pattern above.

Answer 30

what is h hours?

Answer 31

The pattern is the hourly salary, $7, times the number of hours.
Now the number of hours is h.
What is the hourly salary times h?

Answer 32

for 5 hours she earns 35 for 6 she earns 42

Answer 33

h is the variable we chose above to represent the number of hours Tiya worked.

For working 1 hour, Tiya earns 7 * 1
For working 2 hours, Tiya earns 7 * 2
For working 3 hours, Tiya earns 7 * 3
For working 4 hours, Tiya earns 7 * 4
etc.
For working h hours, Tiya earns _______

Answer 34

for 7 she earns 49

Answer 35

for 8 she earns 56

Answer 36

Yes you are correct, but you can't name every different number of hours she works, so we need a general expression to show how much she earns.
We use the variable h to represent the number of hours.
We have seen that when you multiply 7 by the number of hours, you have what she earned.
If she works h hours, she earns 7 times h.
7 times h = 7 * h = 7h

Answer 37

This means the answer to Part C. is
s = 7h

Answer 38

so what is c

Answer 39

ok thx

Answer 40

thats it just s = 7h

Answer 41

Remember from part A. s = salary and h = number of hours Tiya worked.
s = 7h means that the amount of money Tiya earns is always 7 times the number of hours she works.

Answer 42

Yes.
Part C. is simply:
s = 7h
