A roller skating offers a special rate for birthday parties. On the same day, a party for 10 skates cost $107 and a party for 15 skaters cost $137. A) write a linear equation in point-slope form.
B) Find the cost of 12 skaters.

128

Step-by-step explanation:

137-107/15-10

M=7.4 or 7

Equation using (10,107)

Y-107=7(x-10)

Substitute 12 for x

Y-107=7(12-9)

Simplify the right side

Y-107 = 21

Solve for y

Y-107+107= 21+107

Y=128

A party For 12 skaters would cost $128
