Question

Diana is a homebound teacher who charges $45 per hour plus an additional flat fee of $20 for travel. The equation that represents this situation is y = 45x + 20, where x represents the number of hours of classes and y represents the total cost.
Another teacher, Paula, creates a graph comparing the total amount Diana charges for a session and the total amount she charges for a session. Paula finds her graph is shifted below Diana's line, and her line is also steeper than Diana's line.

Select the true statement.


A: Paula charges less per hour and has a lower travel fee.
B: Paula charges more per hour but has a lower travel fee.
C: Paula charges less per hour but has a higher travel fee.
D: Paula charges more per hour and has a higher travel fee.

Answer 1

Paula charges more per hour (to make it steeper) and has a lower travel fee (shift below Diana line)

Hope this help!
