Answer 3

Calculation of the Number of Refrigerators Sent to Schools

To calculate the number of refrigerators that were sent to schools, we need to determine the remaining percentage of refrigerators after sending some to hospitals and daycare centers.

Given the following information: - Total number of refrigerators produced during the cleanup: 250 - 2/5 of these refrigerators were sent to hospitals. - 30% of the remaining refrigerators were sent to daycare centers. - The rest of the refrigerators were sent to schools.

Let's break down the calculation step by step:

1. Calculate the number of refrigerators sent to hospitals: - 2/5 of 250 refrigerators = (2/5) * 250 = 100 refrigerators sent to hospitals.

2. Calculate the remaining refrigerators after sending some to hospitals: - Remaining refrigerators = Total refrigerators - Refrigerators sent to hospitals - Remaining refrigerators = 250 - 100 = 150 refrigerators.

3. Calculate the number of refrigerators sent to daycare centers: - 30% of the remaining refrigerators = (30/100) * 150 = 45 refrigerators sent to daycare centers.

4. Calculate the number of refrigerators sent to schools: - Remaining refrigerators after sending some to daycare centers = Remaining refrigerators - Refrigerators sent to daycare centers - Remaining refrigerators after sending some to daycare centers = 150 - 45 = 105 refrigerators.

Therefore, 105 refrigerators were sent to schools.
