1point(s) the capacity of an elevator is either 30 children or 24 adults. if 20 children are currently in the elevator, how many adults can still enter it?

I would put the equation into two fractions to make a proportion.

30/24 = 20/x

From there, you'd cross multiply to get:

30x = 480

x = 16

So, if there are 20 children currently in the elevator, 16 adults can still enter.

108

Ithink the answer is $2.10
