Answer:

  • 1) 4812 students
  • 2) 763 pounds
  • 3) $30906.76

Step-by-step explanation:

1)

  • Initial number = 2988
  • Rate of increase = 10%

<u>Number of students after 6 years:</u>

  • a_6 = 2988(1+0.1)^{6-1} = 4812

2)

  • Initial number = 1200
  • Rate of decrease = 14%

<u>Amount of gold after 4 years:</u>

  • a_4=1200(1-0.14)^3 = 763

3)

  • Initial number = 28000
  • Rate of increase = 2.5%

a)

<u>Salary after n years:</u>

  • a_n=28000(1+0.025)^{n-1} = 28000*1.025^{n-1}

b)

<u>Salary in the 5th year:</u>

  • a_5=28000*1.025^4 = 30906.76
