Question

if I have 77 days and 6 subjects to study that each have 8 units and 12 lessons in each unit. How much do I have to study each day?

Answer 1

To determine how much you need to study each day, we can start by calculating the total number of lessons across all subjects.

1. **Calculate the total number of lessons**:
- You have 6 subjects.
- Each subject has 8 units.
- Each unit has 12 lessons.

The total number of lessons can be calculated as follows:

\[
\text{Total Lessons} = \text{Number of Subjects} \times \text{Units per Subject} \times \text{Lessons per Unit}
\]

Substituting in the numbers:

\[
\text{Total Lessons} = 6 \times 8 \times 12
\]
\[
\text{Total Lessons} = 6 \times 96 = 576 \text{ lessons}
\]

2. **Calculate how many lessons to study each day**:
You have 77 days to study, so now we divide the total number of lessons by the number of days:

\[
\text{Lessons per Day} = \frac{\text{Total Lessons}}{\text{Number of Days}} = \frac{576}{77}
\]
\[
\text{Lessons per Day} \approx 7.47
\]

Since you can't study a fraction of a lesson, you would need to round this up to 8 lessons on some days, and you could have days where you study 7 lessons to balance it out.

### Summary:
On average, you need to study approximately 7 to 8 lessons per day over the course of 77 days.
