Answer:_______________

The number of students entrolled in a school is 1601. If the entrollement increases by 4 % every year , how many students will be there after 4 years

Answer: 1873

SOLUTION 1 :

Given:

P = 1601

n =4 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1601[1+(4÷100)]^{^n1}

=1601[1+0.04]⁴

= 1601(1.04)⁴

= 1601 x 1.16985856

= 1873

The number of students entrolled in a school is 2426. If the entrollement increases by 4 % every year , how many students will be there after 3 years

Answer: 2729

SOLUTION 1 :

Given:

P = 2426

n =3 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2426[1+(4÷100)]^{^n1}

=2426[1+0.04]³

= 2426(1.04)³

= 2426 x 1.124864

= 2729

The number of students entrolled in a school is 2875. If the entrollement increases by 3 % every year , how many students will be there after 2 years

Answer: 3050

SOLUTION 1 :

Given:

P = 2875

n =2 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2875[1+(3÷100)]^{^n1}

=2875[1+0.03]²

= 2875(1.03)²

= 2875 x 1.0609

= 3050

The number of students entrolled in a school is 1582. If the entrollement increases by 5 % every year , how many students will be there after 4 years

Answer: 1923

SOLUTION 1 :

Given:

P = 1582

n =4 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1582[1+(5÷100)]^{^n1}

=1582[1+0.05]⁴

= 1582(1.05)⁴

= 1582 x 1.21550625

= 1923

The number of students entrolled in a school is 1955. If the entrollement increases by 5 % every year , how many students will be there after 3 years

Answer: 2263

SOLUTION 1 :

Given:

P = 1955

n =3 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1955[1+(5÷100)]^{^n1}

=1955[1+0.05]³

= 1955(1.05)³

= 1955 x 1.157625

= 2263

The number of students entrolled in a school is 2589. If the entrollement increases by 3 % every year , how many students will be there after 2 years

Answer: 2747

SOLUTION 1 :

Given:

P = 2589

n =2 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2589[1+(3÷100)]^{^n1}

=2589[1+0.03]²

= 2589(1.03)²

= 2589 x 1.0609

= 2747

The number of students entrolled in a school is 1281. If the entrollement increases by 2 % every year , how many students will be there after 2 years

Answer: 1333

SOLUTION 1 :

Given:

P = 1281

n =2 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1281[1+(2÷100)]^{^n1}

=1281[1+0.02]²

= 1281(1.02)²

= 1281 x 1.0404

= 1333

The number of students entrolled in a school is 1261. If the entrollement increases by 3 % every year , how many students will be there after 2 years

Answer: 1338

SOLUTION 1 :

Given:

P = 1261

n =2 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1261[1+(3÷100)]^{^n1}

=1261[1+0.03]²

= 1261(1.03)²

= 1261 x 1.0609

= 1338

The number of students entrolled in a school is 2085. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 2255

SOLUTION 1 :

Given:

P = 2085

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2085[1+(4÷100)]^{^n1}

=2085[1+0.04]²

= 2085(1.04)²

= 2085 x 1.0816

= 2255

Answer: 2544

SOLUTION 1 :

Given:

P = 2328

n =3 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2328[1+(3÷100)]^{^n1}
