Q. Tyee was offered a job that paid a salary of $76,000 \$ 76,000 in its first year. The salary was set to increase by 3% 3 \% per year every year. If Tyee worked at the job for 1010 years, what was the total amount of money earned over the 1010 years, to the nearest whole number?\newlineAnswer:
  1. Identify Salary and Rate: Identify the initial salary and the annual increase rate.\newlineTyee's initial salary is $76,000\$76,000, and it increases by 3%3\% each year.
  2. 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.\newlineThe formula for the salary in the nthn^{\text{th}} year is:\newlineSalaryn=Initial Salary×(1+rate)n\text{Salary}_n = \text{Initial Salary} \times (1 + \text{rate})^n\newlinewhere rate\text{rate} is the annual increase rate (3%3\% or 0.030.03) and nn is the year number.
  3. Calculate Total Over 1010 Years: Calculate the total salary over 1010 years by summing up the salaries for each year.\newlineLet's denote the total salary by StotalS_{\text{total}}.\newlineStotal=Salary1+Salary2++Salary10S_{\text{total}} = \text{Salary}_1 + \text{Salary}_2 + \ldots + \text{Salary}_{10}\newlineWe will calculate each year's salary and add them up.
  4. Calculate Yearly Salaries: Calculate the salary for each year and keep a running total.\newlineYear 11: Salary1=$76,000×(1+0.03)1=$76,000×1.03=$78,280Salary_1 = \$76,000 \times (1 + 0.03)^1 = \$76,000 \times 1.03 = \$78,280\newlineYear 22: Salary2=$76,000×(1+0.03)2=$76,000×1.0609$80,628.40Salary_2 = \$76,000 \times (1 + 0.03)^2 = \$76,000 \times 1.0609 \approx \$80,628.40\newlineYear 33: Salary3=$76,000×(1+0.03)3=$76,000×1.092727$83,047.25Salary_3 = \$76,000 \times (1 + 0.03)^3 = \$76,000 \times 1.092727 \approx \$83,047.25\newlineYear 44: Salary4=$76,000×(1+0.03)4=$76,000×1.12550881$85,538.67Salary_4 = \$76,000 \times (1 + 0.03)^4 = \$76,000 \times 1.12550881 \approx \$85,538.67\newlineYear 55: Salary5=$76,000×(1+0.03)5=$76,000×1.15927407$88,104.69Salary_5 = \$76,000 \times (1 + 0.03)^5 = \$76,000 \times 1.15927407 \approx \$88,104.69\newlineYear 66: Salary6=$76,000×(1+0.03)6=$76,000×1.19384229$90,747.41Salary_6 = \$76,000 \times (1 + 0.03)^6 = \$76,000 \times 1.19384229 \approx \$90,747.41\newlineYear 77: Salary7=$76,000×(1+0.03)7=$76,000×1.22933716$93,469.02Salary_7 = \$76,000 \times (1 + 0.03)^7 = \$76,000 \times 1.22933716 \approx \$93,469.02\newlineYear 88: Salary8=$76,000×(1+0.03)8=$76,000×1.26577698$96,272.71Salary_8 = \$76,000 \times (1 + 0.03)^8 = \$76,000 \times 1.26577698 \approx \$96,272.71\newlineYear 99: Salary9=$76,000×(1+0.03)9=$76,000×1.30317029$99,161.66Salary_9 = \$76,000 \times (1 + 0.03)^9 = \$76,000 \times 1.30317029 \approx \$99,161.66\newlineYear 1010: Salary10=$76,000×(1+0.03)10=$76,000×1.34391626$102,138.16Salary_10 = \$76,000 \times (1 + 0.03)^10 = \$76,000 \times 1.34391626 \approx \$102,138.16\newlineNow, add all the yearly salaries to get the total:\newlineSalary2=$76,000×(1+0.03)2=$76,000×1.0609$80,628.40Salary_2 = \$76,000 \times (1 + 0.03)^2 = \$76,000 \times 1.0609 \approx \$80,628.4000
  5. Find Total Salary: Perform the addition to find the total salary over 1010 years.\newlineStotal$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+$102,138.16S_{\text{total}} \approx \$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 + \$102,138.16\newlineStotal$897,388.97S_{\text{total}} \approx \$897,388.97
  6. Round Total Salary: Round the total salary to the nearest whole number as requested. Stotal$(897,389)S_{\text{total}} \approx \$(897,389)
