A dog groomer is offering 20% off a full groom for one dog, and 15% off for each additional dog. You decide to take your two furry friends to be groomed. Normally, a full groom for each dog costs $65. Assuming there is no sales tax, what is the total discounted price for two dogs to be groomed?

7

step-by-step explanation:

the answer would be 7

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
