Answer:_______________

The number of students entrolled in a school is 1886. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 2041

SOLUTION 1 :

Given:

P = 1886

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1886[1+(2÷100)]^{^n1}

=1886[1+0.02]⁴

= 1886(1.02)⁴

= 1886 x 1.08243216

= 2041

The number of students entrolled in a school is 2486. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 2689

SOLUTION 1 :

Given:

P = 2486

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2486[1+(4÷100)]^{^n1}

=2486[1+0.04]²

= 2486(1.04)²

= 2486 x 1.0816

= 2689

The number of students entrolled in a school is 2801. If the entrollement increases by 5 % every year , how many students will be there after 3 years

Answer: 3243

SOLUTION 1 :

Given:

P = 2801

n =3 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2801[1+(5÷100)]^{^n1}

=2801[1+0.05]³

= 2801(1.05)³

= 2801 x 1.157625

= 3243

The number of students entrolled in a school is 1837. If the entrollement increases by 5 % every year , how many students will be there after 2 years

Answer: 2025

SOLUTION 1 :

Given:

P = 1837

n =2 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1837[1+(5÷100)]^{^n1}

=1837[1+0.05]²

= 1837(1.05)²

= 1837 x 1.1025

= 2025

The number of students entrolled in a school is 2593. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 2805

SOLUTION 1 :

Given:

P = 2593

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2593[1+(4÷100)]^{^n1}

=2593[1+0.04]²

= 2593(1.04)²

= 2593 x 1.0816

= 2805

The number of students entrolled in a school is 2423. If the entrollement increases by 5 % every year , how many students will be there after 3 years

Answer: 2805

SOLUTION 1 :

Given:

P = 2423

n =3 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2423[1+(5÷100)]^{^n1}

=2423[1+0.05]³

= 2423(1.05)³

= 2423 x 1.157625

= 2805

The number of students entrolled in a school is 1988. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 2152

SOLUTION 1 :

Given:

P = 1988

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1988[1+(2÷100)]^{^n1}

=1988[1+0.02]⁴

= 1988(1.02)⁴

= 1988 x 1.08243216

= 2152

The number of students entrolled in a school is 1024. If the entrollement increases by 3 % every year , how many students will be there after 3 years

Answer: 1119

SOLUTION 1 :

Given:

P = 1024

n =3 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1024[1+(3÷100)]^{^n1}

=1024[1+0.03]³

= 1024(1.03)³

= 1024 x 1.092727

= 1119

The number of students entrolled in a school is 1425. If the entrollement increases by 4 % every year , how many students will be there after 4 years

Answer: 1667

SOLUTION 1 :

Given:

P = 1425

n =4 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1425[1+(4÷100)]^{^n1}

=1425[1+0.04]⁴

= 1425(1.04)⁴

= 1425 x 1.16985856

= 1667
