Answer:
0.24 and 1.32
Step-by-step explanation:
you divide 2.28 by 9.5 for the first answer then multiply that answer by 5.5
The equation would be: C = 5.5T, where C is the Cost and T is the number of tubes.
If you divide all of the outputs by the inputs, you will get 5.5. That means it's a proportional relationship. Just multiply the number of tubes by 5.5 and you will have your cost.
