Please help me on 1,3 &4

3.  dad=32 and son=16

4. You cannot do this one without knowing the sum of their ages I believe that there is a typo on your page

Step-by-step explanation:

3. 23+8=32

32 divided by 2 = 16

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
