Answer:
The Amount of money in the account after 28 years is $616,674.5
Step-by-step explanation:
Given as :
The principal amount placed in the account = p = $67,000
The rate of interest = r = 8.25%
The time period of amount in the account = t = 28
Let the Amount of money in the account = $A
Now<u>, From Compound Interest method</u>
Amount = Principal ×
A = p ×
Or, A = $67,000 ×
Or, A = $67,000 ×
Or, A = $67,000 × 9.2041
∴ A = $616,674.7
So, The Amount of money in the account = A = $616,674.5
Hence, The Amount of money in the account after 28 years is $616,674.5 Answer
Answer:
Step-by-step explanation:
We are asked to find the equation of a line given a point and the slope. We will use the point-slope formula.
In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of this line is -4 and the line passes through (-2,5).
- m= -4
- x₁= -2
- y₁ = 5
Substitute the values into the formula.
We are finding the equation of the line, so we should find the slope-intercept form or y=mx+b ( where m is the slope and b is the y-intercept).We must isolate the variable y on one side of the equation.
First, distribute the -4 on the right side of the equation. Multiply each term inside the parentheses by -4.
5 is being subtracted from y. The inverse operation of subtraction is addition, so we will add 5 to both sides of the equation.
The equation of the line is y= -4x -3. The slope of the line is -4 and the y-intercept is -3.
