The Demi earns $100 per hour of teaching drum classes. Demi spends $0 per hour taking spin classes.
According to the equation, Demi earns $100 per hour of teaching drum classes.
The equation B=50t simply states that her earnings are directly proportional to the number of hours she teaches, with a slope of 50.
This means that for every hour she teaches, she earns $50.
To calculate how much Demi spends per hour of taking spin classes, we need to use the graph.
The graph shows that for every hour Demi is in class, she spends $100.
However, we need to keep in mind that this includes the time she spends teaching drum classes.
To isolate the cost of taking spin classes, we need to subtract the amount of money she earns from teaching drum classes.
Step 1: Calculate the amount of money Demi earns per hour of teaching drum classes.
We know that Demi earns $100 per hour of teaching drum classes.
Step 2: Subtract the amount of money Demi earns from teaching drum classes from the total amount of money she spends per hour in class.
Total amount spent per hour in class - amount earned per hour teaching drum classes = amount spent per hour taking spin classes
$100 - $100 = $0
Therefore, Demi spends $0 per hour taking spin classes.
