Let's solve each part step by step.
Part A:
To determine whether Sophia should choose to make 12% more or $4,000 more, we first need to calculate both options.
-
12% of her salary:
\[ \text{Increase from 12%} = 0.12 \times 37,400 = 4,488 \] -
$4,000 increase:
This is straightforward, as it is already given.
Now, we compare the two increases:
- Increase from 12%: $4,488
- Increase from $4,000: $4,000
Comparison: Since $4,488 (12%) is greater than $4,000, Sophia should choose the 12% increase.
Part B:
Now, let's find out how much Sophia will make per hour if she chooses the 12% pay bump.
-
New annual salary: \[ \text{New salary} = 37,400 + 4,488 = 41,888 \]
-
Total hours worked: \[ \text{Total hours} = 42 \text{ hours/week} \times 50 \text{ weeks} = 2,100 \text{ hours} \]
-
Hourly rate: \[ \text{Hourly rate} = \frac{41,888}{2,100} \approx 19.96 \]
So, rounding to the nearest cent, Sophia will make approximately $19.96 per hour if she chooses the higher pay bump.
Part C:
Now, let's compare her current job (after the increase) with the new job.
-
Sophia's increased hourly wage from Part B:
\[ \text{Current hourly rate} = 19.96 \] -
New job's salary: $52,900.
-
New job's weekly hours: \[ \text{Total hours} = 55 \text{ hours/week} \times 50 \text{ weeks} = 2,750 \text{ hours} \]
-
New job's hourly wage: \[ \text{New hourly rate} = \frac{52,900}{2,750} \approx 19.27 \]
Comparison:
- Current job's hourly rate: $19.96
- New job's hourly rate: $19.27
Since $19.96 (current job) is greater than $19.27 (new job), Sophia should continue at her current job based strictly on the hourly rate.
