GC - If the principal amount of money put into a bank is $2000 with a 3.5% rate compounded quarterly, what is the amount after 6
alisha [4.7K]

Given:

Principal amount = $2000

Rate of interest = 3.5% compounded quarterly.

Time = 6 years

To find:

The amount after 6 years.

Solution:

The formula for amount after compound interest is:

A=P\left(1+\dfrac{r}{n}\right)^{nt}

Where, P is principal, r is rate of interest in decimal, n is the number of time interest compounded in an year and t is the number of years.

The interest is compounded quarterly, so n=4.

Substituting P=2000,r=0.035,n=4,t=6, we get

A=2000\left(1+\dfrac{0.035}{4}\right)^{4(6)}

A=2000\left(1+0.00875\right)^{24}

A=2000\left(1.00875\right)^{24}

A=2465.10340

Approximate the value to the nearest hundredth.

A\approx 2465.10

The amount after 6 years us $2465.10. Therefore, the correct option is A.

2. A stock price rose 2.2 points in
Natasha_Volkova [10]

Answer: the total  price change in stock is fall of 3.2 points or -3.2 points.

Step-by-step explanation:

In integers , we use positive integers to show rise in amount whereas we use negative integers to show fall .

Given: A stock price rose 2.2 points in  Week 1.

i.e. +2.2 points rise.

The stock price fell 5.4  points in Week 2.

i.e. fall of -5.4.   (Much greater, than it rose)

The equation to represent the total  price change in stock would be

Total  price change = price rose in  Week 1 +  price fell  in Week 2.

= [+2.2 + (-5.4)] points

= 2.2 - 5.4 points   [ (+)(-) = (-)]

= -3.2 points

Hence, the total  price change in stock is fall of 3.2 points.
