If three dozen cookies cost $9, what is the cost per cookie?

Answers

Answer:

$0.25 is the cost per cookie

Step-by-step explanation:

Unit rate defined as the rate are expressed as a quantity as 1 such as 4 meter per second or 4 miles per hour

As per the statement:

If three dozen cookies cost $9.

Use conversion:

1 dozen = 12

then;

3 dozen = 36

then;

36 cookies cost $9.

Cost of cookies = $9

Number of cookies = 36

Then by unit rate definition we have;

$\text{Cost per cookies} = \frac{\text{Cost}}{\text{Number of cookies}} = (9)/(36)$

⇒ $\text{Cost per cookies} = (1)/(4) = \$ 0.25$

Therefore, $0.25 is the cost per cookie

25 cents per cookie
