Problem Analysis

To solve this problem, we need to determine the total number of packages of pastries and pies that were delivered to the store. We know that there were 21 boxes of pastries, with each box containing 20 pastries and an equal number of pies. The pastries are packaged in sets of 30.

Solution

To find the total number of packages of pastries and pies, we can follow these steps:

1. Calculate the total number of pastries delivered: - Each box contains 20 pastries. - Multiply the number of boxes (21) by the number of pastries per box (20) to get the total number of pastries. - Total number of pastries = 21 boxes * 20 pastries per box = 420 pastries.

2. Calculate the total number of pies delivered: - Since each box contains an equal number of pies, the number of pies is the same as the number of pastries. - Total number of pies = 420 pies.

3. Calculate the total number of packages of pastries: - Each package contains 30 pastries. - Divide the total number of pastries by the number of pastries per package (30) to get the total number of packages. - Total number of packages of pastries = 420 pastries / 30 pastries per package = 14 packages.

4. Calculate the total number of packages of pies: - Since each box contains an equal number of pies, the number of packages of pies is the same as the number of boxes. - Total number of packages of pies = 21 packages.

5. Calculate the total number of packages of pastries and pies: - Add the total number of packages of pastries and the total number of packages of pies. - Total number of packages of pastries and pies = 14 packages of pastries + 21 packages of pies = 35 packages.

Therefore, a total of 35 packages of pastries and pies were delivered to the store.

Answer

A total of 35 packages of pastries and pies were delivered to the store.
