Kristen opened a savings account and deposited $800.00. The account earns 7% interest, compounded annually. If she wants to use the money to buy a new bicycle in 3 years, how much will she be able to spend on the bike?

Answers

Answer 1
Answer:

Answer: she will be able to spend $980 on the bike.

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $800

r = 7% = 7/100 = 0.07

n = 1 because it was compounded once in a year.

t = 3 years

Therefore,.

A = 800(1 + 0.07/1)^1 × 3

A = 800(1 + 0.07)^3

A = 800(1.07)^3

A = $980

A rectangle measures fourteen centimetrers by four centimetres what is its area

Answers

The formula for finding the area of a rectangle is:
\sf area = length * width

Here we are given that the length is 14 cm, and the width is 4 cm.

So the are will be:

\sf area = 14~cm * 4~cm\n\n\boxed{\sf{area = 56 cm^2}}
The rectangles area is 56 cm. messed it up the first time!! lol
