Mr cham start a new job with an annual salary of 6400, which increase by 240 every year. After working for eight years. Mr cham promoted to a new job with salary of 9,500 which increase by 360 every year.

Calculate his salary after fifteenth years of service

To calculate Mr. Cham's salary after fifteen years of service, we need to consider his salary for the first eight years and then the next seven years in his promoted job.

For the first eight years:
Annual salary = $6,400
Increase per year = $240

Let's calculate his salary after eight years:
Salary after eight years = Annual salary + (Increase per year * Number of years)
Salary after eight years = $6,400 + ($240 * 8)
Salary after eight years = $6,400 + $1,920
Salary after eight years = $8,320

Now, Mr. Cham is promoted after eight years with a new job and a new salary.

Annual salary in the new job = $9,500
Increase per year = $360

Let's calculate his salary for the next seven years:
Salary for the next seven years = Annual salary + (Increase per year * Number of years)
Salary for the next seven years = $9,500 + ($360 * 7)
Salary for the next seven years = $9,500 + $2,520
Salary for the next seven years = $12,020

Finally, we can calculate his salary after fifteen years of service by adding the salary for the first eight years and the salary for the next seven years:

Total salary after fifteen years of service = Salary after eight years + Salary for the next seven years
Total salary after fifteen years of service = $8,320 + $12,020
Total salary after fifteen years of service = $20,340

Therefore, Mr. Cham's salary after fifteen years of service is $20,340.

To calculate Mr. Cham's salary after 15 years of service, we need to consider two scenarios: the first 8 years when he had a salary of $6,400 increasing by $240 every year, and the next 7 years when he had a salary of $9,500 increasing by $360 every year.

Let's break down the calculation step by step:

First, let's determine his salary after 8 years of service:
Starting salary: $6,400
Increase per year: $240
Years of service: 8

To calculate his salary after 8 years, we can use the formula:
Final Salary = Starting Salary + (Increase per year * Years of service)

Final Salary = $6,400 + ($240 * 8)
Final Salary = $6,400 + $1,920
Final Salary = $8,320

Now, let's determine his salary for the next 7 years:
Starting salary: $9,500
Increase per year: $360
Years of service: 7

To calculate his salary after 7 years, we can use the same formula:
Final Salary = Starting Salary + (Increase per year * Years of service)

Final Salary = $9,500 + ($360 * 7)
Final Salary = $9,500 + $2,520
Final Salary = $12,020

Finally, we can calculate his salary after 15 years of service by adding the salaries from the two scenarios:
Total Salary = Salary after 8 years + Salary after 7 years
Total Salary = $8,320 + $12,020
Total Salary = $20,340

Therefore, Mr. Cham's salary after 15 years of service would be $20,340.

To calculate Mr. Cham's salary after fifteen years of service, we need to calculate his salary for each of the two jobs separately and then add them together.

First, let's calculate Mr. Cham's salary for the first eight years in his initial job:

Year 1: $6,400
Year 2: $6,400 + $240 = $6,640
Year 3: $6,640 + $240 = $6,880
Year 4: $6,880 + $240 = $7,120
Year 5: $7,120 + $240 = $7,360
Year 6: $7,360 + $240 = $7,600
Year 7: $7,600 + $240 = $7,840
Year 8: $7,840 + $240 = $8,080

Now, let's calculate Mr. Cham's salary for the next seven years in his new job:

Year 9: $9,500
Year 10: $9,500 + $360 = $9,860
Year 11: $9,860 + $360 = $10,220
Year 12: $10,220 + $360 = $10,580
Year 13: $10,580 + $360 = $10,940
Year 14: $10,940 + $360 = $11,300
Year 15: $11,300 + $360 = $11,660

Now, let's add the salaries together:

For the first eight years: $8,080
For the next seven years: $11,660

Total salary after fifteen years of service:
$8,080 + $11,660 = $19,740

Therefore, Mr. Cham's salary after fifteen years of service will be $19,740.
