Answer:
A. The point (0,0) shows that the cost is $0 for 0 kg of cashews.
C. The point (2,60) shows that it cost $60 for 2 kg of cashews.
B. The constant of proportionality for this graph is 30.
Step-by-step explanation:
D is wrong
In order to find out what deal is better:
- We have to find the unit rate for each deal
- Total amount of paper towels ÷ The price
So it would be....
- 18 ÷ 14 = 1.285714
- 12 ÷ 10 = 1.2
Short Answer:
The better deal is 10 rolls of paper towels for $12.
Long Answer:
I wanted to find out the price per roll of paper towel for each deal so I created a unit rate problem which is the numerator divided by the denominator. From there, I was able to get my answers, compare which one was less than the other, and select the best deal.

The answer:
(-11,-4) and (8,11/2)
All you do is divide the second equation by y and set them equal to each other. Then solve for y and you get a quadratic. Just solve that and u get the answer.
