Q. Tyee was offered a job that paid a salary of $76,000 in its first year. The salary was set to increase by 3% per year every year. If Tyee worked at the job for 10 years, what was the total amount of money earned over the 10 years, to the nearest whole number?Answer:
Identify Salary and Rate: Identify the initial salary and the annual increase rate.Tyee's initial salary is $76,000, and it increases by 3% each year.
Calculate Yearly Salaries: Calculate the salary for each year using the formula for compound interest, which is applicable here since the salary increases by a fixed percentage each year.The formula for the salary in the nth year is:Salaryn=Initial Salary×(1+rate)nwhere rate is the annual increase rate (3% or 0.03) and n is the year number.
Calculate Total Over 10 Years: Calculate the total salary over 10 years by summing up the salaries for each year.Let's denote the total salary by Stotal.Stotal=Salary1+Salary2+…+Salary10We will calculate each year's salary and add them up.
Calculate Yearly Salaries: Calculate the salary for each year and keep a running total.Year 1: Salary1=$76,000×(1+0.03)1=$76,000×1.03=$78,280Year 2: Salary2=$76,000×(1+0.03)2=$76,000×1.0609≈$80,628.40Year 3: Salary3=$76,000×(1+0.03)3=$76,000×1.092727≈$83,047.25Year 4: Salary4=$76,000×(1+0.03)4=$76,000×1.12550881≈$85,538.67Year 5: Salary5=$76,000×(1+0.03)5=$76,000×1.15927407≈$88,104.69Year 6: Salary6=$76,000×(1+0.03)6=$76,000×1.19384229≈$90,747.41Year 7: Salary7=$76,000×(1+0.03)7=$76,000×1.22933716≈$93,469.02Year 8: Salary8=$76,000×(1+0.03)8=$76,000×1.26577698≈$96,272.71Year 9: Salary9=$76,000×(1+0.03)9=$76,000×1.30317029≈$99,161.66Year 10: Salary10=$76,000×(1+0.03)10=$76,000×1.34391626≈$102,138.16Now, add all the yearly salaries to get the total:Salary2=$76,000×(1+0.03)2=$76,000×1.0609≈$80,628.400
Find Total Salary: Perform the addition to find the total salary over 10 years.Stotal≈$78,280+$80,628.40+$83,047.25+$85,538.67+$88,104.69+$90,747.41+$93,469.02+$96,272.71+$99,161.66+$102,138.16Stotal≈$897,388.97
Round Total Salary: Round the total salary to the nearest whole number as requested. Stotal≈$(897,389)
