Final answer:
Nestor will save a total of $64 in 7 weeks.
Step-by-step explanation:
To calculate how much money Nestor will save in 7 weeks, we can use the concept of exponential growth. Nestor doubles the amount he saved each week. In the first week, he saves $1. In the second week, he doubles that amount to $2. In the third week, he doubles $2 to $4, and so on.
Using this pattern, we can calculate the amount Nestor will save in 7 weeks:
- Week 1: $1
- Week 2: $2
- Week 3: $4
- Week 4: $8
- Week 5: $16
- Week 6: $32
- Week 7: $64
Therefore, Nestor will save a total of $64 in 7 weeks.
