Alice is able to produce 3 dozen cupcakes in 90 minutes. How many cupcakes can she produce in 8 hours?

To determine how many cupcakes Alice can produce in 8 hours, we start by calculating her rate of production.

- Alice produces 3 dozen cupcakes in 90 minutes. Since 1 dozen equals 12 cupcakes, she produces:
  \[
  3 \times 12 = 36 \text{ cupcakes in 90 minutes.}
  \]

- Next, we calculate how many cupcakes Alice can make per minute:
  \[
  \frac{36 \text{ cupcakes}}{90 \text{ minutes}} = 0.4 \text{ cupcakes per minute.}
  \]

- Now, let's calculate how many minutes are in 8 hours:
  \[
  8 \text{ hours} \times 60 \text{ minutes/hour} = 480 \text{ minutes.}
  \]

- Finally, we calculate how many cupcakes Alice can produce in 480 minutes:
  \[
  0.4 \text{ cupcakes/minute} \times 480 \text{ minutes} = 192 \text{ cupcakes.}
  \]

So, Alice can produce **192 cupcakes** in 8 hours.

Here are some related questions to deepen your understanding:
1. How many cupcakes can Alice produce in 5 hours?
2. If Alice’s rate of production increases by 20%, how many cupcakes would she produce in 8 hours?
3. How long would it take Alice to produce 100 cupcakes?
4. If Alice worked for 6 hours instead of 8, how many cupcakes would she make?
5. How many cupcakes could two people working at the same rate produce in 8 hours?

**Tip**: When dealing with rates of production, always find a unit rate (per minute, per hour, etc.) to make scaling calculations easier.

Find out how many cupcakes Alice can produce in 8 hours based on her rate of production: 3 dozen in 90 minutes. This problem involves unit rate calculation and time conversion, perfect for Grades 5-7 students.
