we have

3n+16=7n

Solve for n

Subtract 3n both sides

3n+16-3n=7n-3n

4n=16

Divide by 4 both sides

4n/4=16/4

n=4

n=4

Licemer1 [7]

The amount for the investment of $6000 will be a.$6369  b. $6090  and c.$6030.

<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

A=P[1+\dfrac{r}{n}]^{nt}

a) The amount in the bank after 6 years if interest is compounded annually.

A=P[1+\dfrac{r}{1}]^{t}\\\\\\A=6000[1+\dfrac{0.01}{1}]^{  6}

A= $6369

b) The amount in the bank after 6 years if interest is compounded quarterly.

A=P[1+\dfrac{r}{4}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{4}]^{4\times 6}

A= $6090

c ) The amount in the bank after 6 years if interest is compounded monthly.

A=P[1+\dfrac{r}{12}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{12}]^{12\times 6}

A=$6030

Hence the amount for the investment of $6000 will be a.$6369  b. $6090  and c.$6030.

Black_prince [1.1K]

Answer:

5.98

Step-by-step explanation:

2.99 * 1= 2.99

2.99+2.99= 5.98

First you had to multiply 2.99 by 1 because 100% in decimal is 1.

You get 2.99 and you add it to the original price.

And that is how you get 5.98
