An investor puts $200 in an account that pays 7% interest, compounded annually. Find the amount in the account after 3 years.

the amount in the account after 3 years is $245

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 = 200

r = 7% = 7/100 = 0.07

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

t = 3 years

Therefore,

A = 200(1+0.07/1)^1 × 3

A = 200(1+0.07)^3

A = 200(1.07)^3

A = $245

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
