At the Flyer Factory, the assembly line produces 102 computers in a batch. The computers are packaged in boxes with 25 each. If 10 batches are made in one day, how many computers will be leftover at the end of it?

To find out how many computers will be leftover at the end of the day, we can follow these steps: 1. **Calculate the total number of computers produced in one day:** \[ \text{Total computers} = \text{Number of batches} \times \text{Computers per batch} = 10 \times 102 = 1020 \] 2. **Calculate how many boxes can be filled with the total number of computers:** \[ \text{Boxes filled} = \frac{\text{Total computers}}{\text{Computers per box}} = \frac{1020}{25} = 40.8 \] Since we can only fill whole boxes, we can fill 40 boxes. 3. **Calculate the total number of computers in the filled boxes:** \[ \text{Computers in filled boxes} = \text{Boxes filled} \times \text{Computers per box} = 40 \times 25 = 1000 \] 4. **Calculate the number of leftover computers:** \[ \text{Leftover computers} = \text{Total computers} - \text{Computers in filled boxes} = 1020 - 1000 = 20 \] Therefore, the number of computers that will be leftover at the end of the day is **20**.
