Final answer:
The strawberry picker will earn $3 after filling 9 pint boxes as they earn $1 for every 3 pint boxes filled.
Step-by-step explanation:
The strawberry picker earns money based on the number of pint boxes they fill. For every 3 pint boxes filled, they earn $1. To solve how much they would earn after filling 9 pint boxes, we divide the total number of pint boxes by 3 and then multiply the result by the earning per 3 pint boxes.
- Number of pint boxes filled: 9
- Divide this number by 3 (the number of pint boxes required to earn $1): 9 ÷ 3 = 3
- Now multiply the result by $1 (the amount earned for every 3 pint boxes): 3 × $1 = $3
Therefore, after filling 9 pint boxes, the strawberry picker will earn $3.
