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

$52

Step-by-step 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

For the answer to the question above, first you have to do is to take the number of days d that the temperature was above 90 in April, divide by 30, the total number of days in April, and then multiply by 100. probability = d/30 * 100

Probability = 5/30 * 100
                  = 16.67

16.67 is the probability. I hope this helps.
