Please help! Need an equation using C and S and points to graph.

see below

Step-by-step explanation:

The cost is the flat fee of 5200 plus the amount per ton

C = 5200 + 200S

Let S =0

Then C = 5200

Let S = 1

C = 5200+200 = 5400

C = 5200 + 200S

Draw a straight line (only in the first quadrant) connecting the following two points:

(0, 5200)

(10, 7200)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

47 - 90 = 43

43 - 180 = x

x = 137
