Answer:
The point is (7,0).
Step-by-step explanation:
The equation of a linear function in point-slope form is as follows :
...(1)
Where
(x₁,y₁) are the coordinates of the point which the line passes through it and (x,y).
Harold correctly wrote the equation y= 3(x–7)
or we can write it as :
y-0=3(x-7) ...(2)
Comparing equations (1) and (2), we get :
x₁ = 7 and y₁ = 0
So, the point is (7,0).
The correct option is (c).
He pays in interest of $111.0375. Interest is calculated in the two ways, by compounding or by simple interest.
<h3>How to calculate simple interest amount?</h3>
If the initial amount (also called as principal amount) is P, and the interest rate is R % annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
The given data in the problem is;
The principal is,P=$2700
The rate of interest = 3.5%
The total time interval is,T
The total time interval is;
The simple interest is found as;
Hence, he pays in interest of $111.0375.
