The number of students entrolled in a school is 2940. 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 1637. If the entrollement increases by 5 % every year , how many students will be there after 2 years

Answer: 1805

SOLUTION 1 :

Given:

P = 1637

n =2 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1637[1+(5÷100)]^{^n1}

=1637[1+0.05]²

= 1637(1.05)²

= 1637 x 1.1025

= 1805

The number of students entrolled in a school is 1757. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 1902

SOLUTION 1 :

Given:

P = 1757

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1757[1+(2÷100)]^{^n1}

=1757[1+0.02]⁴

= 1757(1.02)⁴

= 1757 x 1.08243216

= 1902

The number of students entrolled in a school is 2056. If the entrollement increases by 3 % every year , how many students will be there after 2 years

Answer: 2181

SOLUTION 1 :

Given:

P = 2056

n =2 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2056[1+(3÷100)]^{^n1}

=2056[1+0.03]²

= 2056(1.03)²

= 2056 x 1.0609

= 2181

The number of students entrolled in a school is 2154. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 2332

SOLUTION 1 :

Given:

P = 2154

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2154[1+(2÷100)]^{^n1}

=2154[1+0.02]⁴

= 2154(1.02)⁴

= 2154 x 1.08243216

= 2332

The number of students entrolled in a school is 2089. If the entrollement increases by 2 % every year , how many students will be there after 3 years

Answer: 2217

SOLUTION 1 :

Given:

P = 2089

n =3 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2089[1+(2÷100)]^{^n1}

=2089[1+0.02]³

= 2089(1.02)³

= 2089 x 1.061208

= 2217

The number of students entrolled in a school is 1140. If the entrollement increases by 4 % every year , how many students will be there after 2 years

Answer: 1233

SOLUTION 1 :

Given:

P = 1140

n =2 years

r = 4%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1140[1+(4÷100)]^{^n1}

=1140[1+0.04]²

= 1140(1.04)²

= 1140 x 1.0816

= 1233

The number of students entrolled in a school is 2599. If the entrollement increases by 5 % every year , how many students will be there after 4 years

Answer: 3159

SOLUTION 1 :

Given:

P = 2599

n =4 years

r = 5%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2599[1+(5÷100)]^{^n1}

=2599[1+0.05]⁴

= 2599(1.05)⁴

= 2599 x 1.21550625

= 3159

The number of students entrolled in a school is 1328. If the entrollement increases by 3 % every year , how many students will be there after 4 years

Answer: 1495

SOLUTION 1 :

Given:

P = 1328

n =4 years

r = 3%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 1328[1+(3÷100)]^{^n1}

=1328[1+0.03]⁴

= 1328(1.03)⁴

= 1328 x 1.12550881

= 1495

The number of students entrolled in a school is 2840. If the entrollement increases by 2 % every year , how many students will be there after 4 years

Answer: 3074

SOLUTION 1 :

Given:

P = 2840

n =4 years

r = 2%

Appreciation :

A = P[1+(r÷100)]ⁿ

= 2840[1+(2÷100)]^{^n1}

=2840[1+0.02]⁴

= 2840(1.02)⁴

= 2840 x 1.08243216

= 3074
