Question

Evan has a summer job to pick berries on a farm.
He earns $2.00 every 15 minutes that he picks strawberries.
He earns $2.40 for every 15 minutes that he picks blueberries.
He picked strawberries for an hour and blueberries for 45 minutes.
How much money did Evan earn?

Answer 1

To calculate how much money Evan earned, we first need to determine how much time he spent picking strawberries and blueberries, and then calculate his earnings based on his pay rate.

1. **Picking Strawberries:**
- Evan picked strawberries for 1 hour.
- 1 hour = 60 minutes.
- In 15 minutes, he earns $2.00.
- Therefore, in 60 minutes, he can break it down as follows:
- \( 60 \text{ minutes} \div 15 \text{ minutes} = 4 \) groups of 15 minutes.
- His earnings for 60 minutes of picking strawberries:
\[
4 \times 2.00 = 8.00
\]
- So, he earned **$8.00** from picking strawberries.

2. **Picking Blueberries:**
- Evan picked blueberries for 45 minutes.
- In 15 minutes, he earns $2.40.
- Therefore, in 45 minutes:
- \( 45 \text{ minutes} \div 15 \text{ minutes} = 3 \) groups of 15 minutes.
- His earnings for 45 minutes of picking blueberries:
\[
3 \times 2.40 = 7.20
\]
- So, he earned **$7.20** from picking blueberries.

3. **Total Earnings:**
- Now, we add his earnings from both activities:
\[
8.00 + 7.20 = 15.20
\]

Thus, Evan earned a total of **$15.20**.
