Sagot :

Answer:

The cost of 3 lessons would be $70, and Marlowe can have 4 lessons without exceeding $100.

Step-by-step explanation:

Number of Lessons & Costs

0- 10

2- 50

4- 90

6.- 130

The equation for this would be y = 20x + 10

To find the price for 3 lessons, plug 3 as x in the equation

y = 20(3) + 10 = 70

The cost for 3 lessons would be $70

20(4) + 10 = 90

20(5) + 10 = 110

5 lessons would be $10 over. With $100, Marlowe will be able to have 10 lessons with $10 left.
P.S., Sorry I can't graph it too, and sorry I didn't respond as  quickly as I would.
