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.
