Question

Terrell's mom paid $27 for 18 juice boxes for the party. at that rate, how much would she pay for 24 juice boxes?

Answer 1

This is an item involving the use of ratio and proportion. The ratio between the the cost and the number of juice boxes should always be equal. With this,  
                                ($27 / 18 juice boxes) = (x / 24 juice boxes)
Solving x from the equation gives x = 36. Thus, 24 juice boxes cost $36.
