Fancy Nails charges $28 for a pedicure plus $9 for each treatment. Lara's Nails charges $22 for a pedicure plus $11 per treatment.
How many treatments need to be purchased for the cost at both places to be the same?

(1 Point)
y = 9x + 28 & y = 11x + 22

It's B.3

Step-by-step explanation:

Substitution. With the equation Y= 9x+28 and Y= 11x+22, you substitute the x-factor with '3'. Which will give you

Y= 9(3)+28         Y= 11(3)+22

Y= 27+28           Y= 33+22

Y= 55                 Y= 55

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
