Step-by-step explanation:

Step-by-step explanation:

1/3(9k+12)=15

We move all terms to the left:

1/3(9k+12)-(15)=0

Domain of the equation: 3(9k+12)!=0

k∈R

We multiply all the terms by the denominator

-15*3(9k+12)+1=0

Wy multiply elements

-45k(9+1= 10

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
