Answer 1

To find out when Ingrid will run out of money, we can see how much money she has at the start of each week and how much she spends each week.

Ingrid starts with $110.00 and spends $18.00 per week. Here's how we calculate the amount left each week:

- Week 1:
- Starting Amount: $110.00
- Amount Spent: $18.00
- Amount Left: $110.00 - $18.00 = $92.00

- Week 2:
- Starting Amount: $92.00
- Amount Spent: $18.00
- Amount Left: $92.00 - $18.00 = $74.00

- Week 3:
- Starting Amount: $74.00
- Amount Spent: $18.00
- Amount Left: $74.00 - $18.00 = $56.00

- Week 4:
- Starting Amount: $56.00
- Amount Spent: $18.00
- Amount Left: $56.00 - $18.00 = $38.00

Now we can continue calculating until she runs out of money.

- Week 5:
- Starting Amount: $38.00
- Amount Spent: $18.00
- Amount Left: $38.00 - $18.00 = $20.00

- Week 6:
- Starting Amount: $20.00
- Amount Spent: $18.00
- Amount Left: $20.00 - $18.00 = $2.00

- Week 7:
- Starting Amount: $2.00
- Amount Spent: $18.00
- Amount Left: $2.00 - $18.00 = -$16.00 (She would run out of money during this week.)

Thus, Ingrid will run out of money at the end of **Week 7**.
