Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

0.1125 kg
Step-by-step explanation:
Step 1:
Let us assume that 48 inches of coil of steel weighs 10.800 kg.
We have to find the weight of 0.5 inch coil.
Step 2:
In this problem we assume that it is given in direct relationship.
Therefore, Problem becomes
48 inches weigh 10.8 kg
0.5 inches weigh X kg
(48 / 0.5) = ( 10.8 / X)
X = (10.8 × 0.5) / 48
X = 0.1125 kg
