The students will earn $
in week 8.

Answer 1

To determine the amount the students will earn in week 8, we first need to identify the pattern in their earnings from weeks 1 to 6.

The earnings for each week are as follows:

• Week 1: $110
• Week 2: $100
• Week 3: $90
• Week 4: $110
• Week 5: $100
• Week 6: $90

From this, we can observe a repeating pattern:

• Weeks 1, 4: $110
• Weeks 2, 5: $100
• Weeks 3, 6: $90

The pattern repeats every three weeks:

• Week 1: $110
• Week 2: $100
• Week 3: $90

If we continue this pattern:

• Week 7 would follow week 6's earning: $110
• Week 8 would follow week 1's earning: $100

Thus, the students will earn $100 in week 8.

So the answer is:

The students will earn $100 in week 8.
