Answer:
No
Step-by-step explanation:
Proportional is when there is a pattern in a graph/table
Answer:
a mix with a total cost of x=$73.
Of course, 30 pounds (50 pounds - 20 pounds = 30 pounds) of that mix will be the more expensive ground beef.
We know that Company B will be less expensive at first, but Company A will become a better option as the miles rack up. Eventually, Company A will be less expensive. There will be a point where the price will be the same for each company.
150 + .20x = Company A
70 + .40x = Company B
If we set these two equations equal to each other, we find out when the price will be the same.
