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

Hope this helps

answer: it depends on what the tax percentage

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
