Using the constant of proportionality that is determined, the true statements are:

B. Option 3 costs the least amount per class.

D. Option 1 costs $1 more per class than option 2 costs per class.

How to Find Constant of Proportionality?

The constant of proportionality, k, between variables y and x is, k = y/x.

Amount = y

Number of classes = x

Constant of proportionality = y/x.

Option 1:

Constant of proportionality = 80/5 = $16 per class

Option 2:

Constant of proportionality = 900/60 = $15 per class

Option 3:

Constant of proportionality = 174/12 = $14.5 per class

The lowest cost per class is Option 3.

Option 1 is $1 more costlier than Option 2.
