Problem 5:
Lulu buys five candy bars for $0.84 each. When she goes to pay, the register takes $0.15 off the total price. How much did Lulu spend on the candy bars?
Step 1: Calculate the total cost before the discount.
Each candy bar costs $0.84 and she buys 5:
$$
5 \times 0.84 = 4.20
$$
Step 2: Subtract the $0.15 discount:
$$
4.20 - 0.15 = 4.05
$$

From the chart:
- Week 1: $125.88
- Week 2: $184.21
- Week 3: $155.01
- Week 4: $149.98
Add all amounts:

310.09 + 155.01 = 465.10 \\
465.10 + 149.98 = 615.08
