The number of students entrolled in a school is 2096. If the entrollement increases by 5 % every year , how many students will be there after 4 years

Answer:_______________

The number of students entrolled in a school is 1650. If the entrollement increases by 5 % every year , how many students will be there after 3 years

Answer: 1910

SOLUTION 1 :

Given:

P = 1650

n =3 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1650[1+(5÷100)]^{^n1}

=1650[1+0.05]³

= 1650(1.05)³

= 1650 x 1.157625

= 1910

The number of students entrolled in a school is 1296. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 1402

SOLUTION 1 :

Given:

P = 1296

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1296[1+(4÷100)]^{^n1}

=1296[1+0.04]²

= 1296(1.04)²

= 1296 x 1.0816

= 1402

The number of students entrolled in a school is 2571. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 2783

SOLUTION 1 :

Given:

P = 2571

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2571[1+(2÷100)]^{^n1}

=2571[1+0.02]⁴

= 2571(1.02)⁴

= 2571 x 1.08243216

= 2783

The number of students entrolled in a school is 1839. If the entrollement increases by 3 % every year , how many students will be there after 4 years

Answer: 2070

SOLUTION 1 :

Given:

P = 1839

n =4 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1839[1+(3÷100)]^{^n1}

=1839[1+0.03]⁴

= 1839(1.03)⁴

= 1839 x 1.12550881

= 2070

The number of students entrolled in a school is 1359. If the entrollement increases by 4 % every year , how many students will be there after 3 years

Answer: 1529

SOLUTION 1 :

Given:

P = 1359

n =3 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1359[1+(4÷100)]^{^n1}

=1359[1+0.04]³

= 1359(1.04)³

= 1359 x 1.124864

= 1529

The number of students entrolled in a school is 2920. If the entrollement increases by 4 % every year , how many students will be there after 3 years

Answer: 3285

SOLUTION 1 :

Given:

P = 2920

n =3 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2920[1+(4÷100)]^{^n1}

=2920[1+0.04]³

= 2920(1.04)³

= 2920 x 1.124864

= 3285

The number of students entrolled in a school is 2340. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 2531

SOLUTION 1 :

Given:

P = 2340

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2340[1+(4÷100)]^{^n1}

=2340[1+0.04]²

= 2340(1.04)²

= 2340 x 1.0816

= 2531

The number of students entrolled in a school is 1859. If the entrollement increases by 5 % every year , how many students will be there after 2 years

Answer: 2050

SOLUTION 1 :

Given:

P = 1859

n =2 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1859[1+(5÷100)]^{^n1}

=1859[1+0.05]²

= 1859(1.05)²

= 1859 x 1.1025

= 2050

Answer: 2389

SOLUTION 1 :

Given:

P = 2064

n =3 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2064[1+(5÷100)]^{^n1}

=2064[1+0.05]³

= 2064(1.05)³

= 2064 x 1.157625

= 2389
