Question

Piano lessons with Ms. Cohen cost $30 for 3/4 of an hour. What is Ms. Cohen's hourly rate?

Answer 1

Answer:

$40.

Step-by-step explanation:

To find the hourly rate, we can divide the price and the time.

We know that Ms.Cohen charges $30 for 3/4 of an hour. So, we will perform:

$30\div\frac{3}{4}$

We dividing fractions, we keep, change, and flip. Hence:

$=30\times\frac{4}{3}$

Multiply:

$=\frac{120}{3}=\ 40$

Therefore, the hourly rate is $40.

And this is the hourly rate because it is $40/1 hour. We can ignore the 1, so it’s just $40 per hour.

Answer 2

Answer:

$40

Step-by-step explanation:

If is $30 for 3/4 then you add 1 more to get 4/4 you get $10 added to $40
