## Answering Questions from “Day 4” Image

### Question 13

A patron returns **3 books** , each **2 weeks overdue**. The overdue fine is **$1 per week per book**.

- Total fine: 3 books × 2 weeks × $1 = $6
- Patron pays $3

The balance shown by the computer = Total fine - Payment = **$6 - $3 = $3 owed** (negative balance indicates amount owed).  
Thus, the balance is **- $3**

**Answer: B. -$3**

* * *

### Question 14

Original balance = $6,356.17  
Payments made: $133.45 × 5 = $667.25  
No interest (APR = 0.0%), so balance reduces by payment amount.

New balance = $6,356.17 - $667.25 = **$5,688.92**

**Answer: F. -$5,688.92**

* * *

### Question 15

- Estimate: 5 workers × 12 hours each = 60 total labor hours
- Actual:
  - 3 workers × 12 hours = 36 hours
  - 2 workers × 10 hours = 20 hours
  - Total = 36 + 20 = 56 hours

Difference = 60 (estimate) - 56 (actual) = 4 hours less than estimated.

**Answer: A. Yes, 4 hours less than estimated**

* * *

### Question 16

- Beach erosion rate = 2 feet per year
- Prediction period = 4 years

Net loss = 2 feet/year × 4 years = **8 feet**

Since beach is eroding, loss is **-8 feet**

**Answer: F. -8 feet**

* * *

Would you like me to provide detailed step-by-step solutions or explanations for any of these problems?

## **Answers to Questions 13–16**

### Key Takeaways

- Overdue fines are calculated by
\text{fine} = (\text{\# of books}) \times (\text{weeks overdue}) \times (\text{rate per week}).
- A balance after payments is
\text{new balance} = \text{original balance} - (\text{payment} \times \text{number of payments}).
- To compare estimated vs. actual labor, sum total hours:
\text{total actual} = \sum (\text{workers} \times \text{hours each}).
- Erosion prediction uses
\text{loss} = (\text{rate per year}) \times (\text{years}).

### Direct Answers

1. D. $3
2. J. $5,688.92
3. A. Yes, 4 hours less than estimated
4. F. −8 feet

## Question 13: Patron’s Balance

A patron returns 3 books each 2 weeks overdue at $1/week/book. Fine = 3 \times 2 \times 1 = \$6. Patron pays $3, so balance owed = $6 − $3 = **$3**.

* * *

## Question 14: Credit Balance After Payments

Original balance = $6,356.17. Monthly payment = $133.45 for 5 months, total payments =

5 \times 133.45 = \$667.25.

New balance = $6,356.17 − $667.25 = **$5,688.92**.

* * *

## Question 15: Project Estimate vs. Actual

Estimate: 5 workers × 12 hours each = 60 hours.  
Actual:

- 3 workers × 12 h = 36 h
- 2 workers × 10 h = 20 h  
Total actual = 36 + 20 = 56 h, which is 4 h less than estimated ⇒ **Yes, 4 hours less**.

* * *

## Question 16: Beach Erosion Prediction

Erosion rate = 2 feet/year for 4 years ⇒ loss = 2 \times 4 = 8 feet. Net loss is **−8 feet**.

## Summary Table

| Question | Concept | Calculation | Answer |
| --- | --- | --- | --- |
| 13 | Overdue fine | 3×2×1=6;\;6−3=3 | D. $3 |
| 14 | Balance after fixed payments | 5×133.45=667.25;\;6356.17−667.25 | J. $5,688.92 |
| 15 | Estimated vs. actual labor | 5×12=60;\;36+20=56;\;60−56=4 | A. 4 h less |
| 16 | Erosion prediction | 2×4=8 | F. −8 feet |

## FAQ

Q1: How do I compute an overdue fine?  
A1: Multiply the number of books × weeks overdue × rate per week.

Q2: Why is the new balance still positive?  
A2: A positive balance means the patron still owes money after payments.

Q3: How to compare estimated vs. actual hours?  
A3: Sum total actual hours and subtract from estimated total.

Q4: What does a negative erosion value indicate?  
A4: “−8 feet” denotes an 8-foot loss of beach.
