Final answer:
To find out how many apples are needed for 8 pies, a proportion is set up based on the rate of 15 apples for 6 pies. The rate is 2.5 apples per pie, so for 8 pies, the baker needs 20 apples.
Step-by-step explanation:
The question asks how many apples are needed to make 8 pies, given the rate of apples to pies based on initial data. According to the information provided, the baker uses 15 apples to make 6 pies. To find out how many apples are needed for 8 pies, we set up a proportion where the number of apples is directly proportional to the number of pies.
First, we calculate the rate of apples to pies, which is 15 apples for 6 pies, therefore:
- 1 pie = 15 apples / 6 pies = 2.5 apples
Next, we multiply the number of apples needed for 1 pie by the total number of pies we want to make:
- 8 pies × 2.5 apples/pie = 20 apples
Therefore, the baker needs 20 apples to make 8 pies.
