Part A:
To determine whether Sophia should choose the 12% higher salary or the $4,000 increase, we need to calculate both options based on her current salary of $37,400.
-
Calculating the 12% increase: \[ 0.12 \times 37,400 = 4,488 \] \[ \text{New salary with 12% increase} = 37,400 + 4,488 = 41,888 \]
-
Calculating the $4,000 increase: \[ \text{New salary with $4,000 increase} = 37,400 + 4,000 = 41,400 \]
Now we compare the two new salaries:
- Salary with 12% increase: $41,888
- Salary with $4,000 increase: $41,400
Since $41,888 (12% increase) is greater than $41,400 ($4,000 increase), Sophia should choose the 12% increase.
Part B:
Now we need to calculate Sophia's hourly wage if she chooses the 12% pay bump.
-
Calculate total hours worked for the year: \[ \text{Total hours} = \text{hours per week} \times \text{weeks per year} = 42 \times 50 = 2,100 \text{ hours} \]
-
Calculate her hourly wage with the new salary: \[ \text{Hourly wage} = \frac{\text{New salary}}{\text{Total hours}} = \frac{41,888}{2,100} \] \[ \text{Hourly wage} \approx 19.97 \]
Therefore, rounding to the nearest cent, Sophia's hourly wage will be $19.97 if she chooses the higher pay bump (12% increase).
