You can solve this by using the system of equations.
Jan - 4.95 = 2H + 3C
Wayne - 5.45 = 3H + 2C

Use elimination.
-3(2H + 3C = 4.95)
2(3H + 2C = 5.45)

Solve. And you'll get:
-6H + (-9C) = -14.85
6H + 4C = 10.9

Cross out -6H and 6H because they cancel out. And you're left with:
-9C = -14.85
4C = 10.9

Add -9C with 4C, and -14.85 with 10.9.
-5C = -3.95

Divide each side with -5.
C = $0.79

Now to figure out what H is, just substitute the C in one of the equations with 0.79.
5.45 = 3H + 2(0.79)
5.45 = 3H + 1.58
-1.58            -1.58
3.87 = 3H
3.87/3 = 3/3(H)
1.29 = H

Determine if the function is proportional. Explain your reasoning.
andriy [413]

Answer:

The ratio \frac{\textrm{Rent}}{\textrm{Number of Days}} is same for every pair of values.

Step-by-step explanation:

See the given graph.

The graph is a straight line which proves that the Rent in dollars is increasing at a constant rate with respect to time in Days. So, for a fixed change in time in Days, there will be a fixed change in the rent in Dollars.

Therefore, yes the function is proportional  and the ratio \frac{\textrm{Rent}}{\textrm{Number of Days}} is same for every pair of values.  

Hence, option 1 is correct.
