Explanation:

Step1: Define 2010 price variable

Let $x$ = 2010 milk price.

Step2: Set up percentage increase equation

2011 price = $x \times (1 + 0.14)$, so:
$1.14x = 2.36$

Step3: Solve for $x$

$x = \frac{2.36}{1.14} \approx 2.07$

---

Step1: Calculate charge difference

Month 3 - Month 2: $0.45 - 0.36 = 0.09$

Step2: Find percentage increase

$\text{Increase \%} = \frac{0.09}{0.36} \times 100\% = 25\%$

---

Step1: Calculate raise amount

$\text{Raise} = 46000 \times 0.045 = 2070$

Step2: Compute new salary

$\text{New Salary} = 46000 + 2070 = 48070$

Answer:

1. F. $2.07
2. D. 25%
3. H. $48,070.00
