Question 6
7. One business charges $12 per t-shirt custom made.

Another business charges $11 per t-shirt plus a $20 set up fee for custom made.

If you were to graph both of these scenarios on the coordinate plane, the first graph would be proportional and the second non proportional.

How would you transform the first graph to make it become a non proportional graph with the same y-intercept as the second graph?

Answer 1

For the first question, to make the cab company's charges a non-proportional situation, you would want to introduce a flat rate. The correct choice would be:

Charge a flat rate of $10 and then $8 per mile.

This introduces a fixed charge that does not depend on the number of miles, making it non-proportional.

For the second question, to transform the first graph (which represents the proportional relationship of charging $12 per t-shirt) into a non-proportional graph with the same y-intercept as the second graph (which has a $20 setup fee), you would need to raise the starting cost. Therefore, the correct choice is:

Up 20.

This means you would add $20 to the cost of each t-shirt, mirroring the setup fee in the second graph.
