To find the amount earned by Victor for 15 weeks, we can analyze the pattern in the table.
From the given data:
- Week 0: $0
- Week 1: $5
- Week 2: $10
- Week 3: $15
- Week 4: $20
We can observe that Victor earns $5 each week. This indicates a linear pattern where the amount earned can be calculated as follows:
\[ \text{Amount earned in week } n = 5 \times n \]
Thus, for 15 weeks (n = 15):
\[ \text{Amount earned in week 15} = 5 \times 15 = 75 \]
Therefore, the total amount earned by Victor after 15 weeks is $75.
