Sunita creates a scale model of an aeroplane. The scale of the model is 4 cm to 13 m.
Sunita's model has a wingspan of 21 cm.
What is the wingspan of the real aeroplane?

i got 86 for this

hope this !

if you need an explanation just ask

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 .
