The number of students entrolled in a school is 2738. If the entrollement increases by 4 % every year , how many students will be there after 4 years

Answer:_______________

The number of students entrolled in a school is 1669. If the entrollement increases by 3 % every year , how many students will be there after 2 years

Answer: 1771

SOLUTION 1 :

Given:

P = 1669

n =2 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1669[1+(3÷100)]^{^n1}

=1669[1+0.03]²

= 1669(1.03)²

= 1669 x 1.0609

= 1771

The number of students entrolled in a school is 2340. If the entrollement increases by 5 % every year , how many students will be there after 4 years

Answer: 2844

SOLUTION 1 :

Given:

P = 2340

n =4 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2340[1+(5÷100)]^{^n1}

=2340[1+0.05]⁴

= 2340(1.05)⁴

= 2340 x 1.21550625

= 2844

The number of students entrolled in a school is 1264. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 1368

SOLUTION 1 :

Given:

P = 1264

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1264[1+(2÷100)]^{^n1}

=1264[1+0.02]⁴

= 1264(1.02)⁴

= 1264 x 1.08243216

= 1368

The number of students entrolled in a school is 2102. If the entrollement increases by 2 % every year , how many students will be there after 3 years

Answer: 2231

SOLUTION 1 :

Given:

P = 2102

n =3 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2102[1+(2÷100)]^{^n1}

=2102[1+0.02]³

= 2102(1.02)³

= 2102 x 1.061208

= 2231

The number of students entrolled in a school is 2483. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 2686

SOLUTION 1 :

Given:

P = 2483

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2483[1+(4÷100)]^{^n1}

=2483[1+0.04]²

= 2483(1.04)²

= 2483 x 1.0816

= 2686

The number of students entrolled in a school is 1703. If the entrollement increases by 5 % every year , how many students will be there after 4 years

Answer: 2070

SOLUTION 1 :

Given:

P = 1703

n =4 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1703[1+(5÷100)]^{^n1}

=1703[1+0.05]⁴

= 1703(1.05)⁴

= 1703 x 1.21550625

= 2070

The number of students entrolled in a school is 1626. If the entrollement increases by 2 % every year , how many students will be there after 2 years

Answer: 1692

SOLUTION 1 :

Given:

P = 1626

n =2 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1626[1+(2÷100)]^{^n1}

=1626[1+0.02]²

= 1626(1.02)²

= 1626 x 1.0404

= 1692

The number of students entrolled in a school is 2652. If the entrollement increases by 2 % every year , how many students will be there after 3 years

Answer: 2814

SOLUTION 1 :

Given:

P = 2652

n =3 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2652[1+(2÷100)]^{^n1}

=2652[1+0.02]³

= 2652(1.02)³

= 2652 x 1.061208

= 2814

The number of students entrolled in a school is 1574. If the entrollement increases by 4 % every year , how many students will be there after 4 years

Answer: 1841

SOLUTION 1 :

Given:

P = 1574

n =4 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1574[1+(4÷100)]^{^n1}

=1574[1+0.04]⁴

= 1574(1.04)⁴

= 1574 x 1.16985856

= 1841

Answer: 3203

SOLUTION 1 :

Given:

P = 2738

n =4 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2738[1+(4÷100)]^{^n1}
