Question

Yhe cost for 7 dance lessons is 82. the cost for 11 dance lessons is 122. write and solve an equation to find the cost of 4 dance lessons

Answer 1

I believe the answer is 44, if not 46. Finding the cost of each dance lesson is the key, but i had a hard time.

Answer 2

$52

Explanation:

(7, 82)

(11, 122)

m= 122-82 40

--------- = -------- = 10

11-7 4

y - 82= 10(x-7)

y - 82= 10x - 70

y= 10x + 12

y= 10(4) + 12

y= $52
