Determine which statement or statements are true. nails used = 6 ; bird houses built = 2

For every 6 nails used there were 2 bird houses built

For every 6 bird houses built there were 2 nails used

The ratio of nails used to bird houses built was 6:2

The ratio of bird houses built to nails used was 2:6

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 .
