Given
Principal 1500
Intrest 6%
Time 240 days
Partial payments for 100th day 7,000
For 180th day 4,000
A. Use the u. s rule to solve for total intrest cost
B. Use the u. s rule to solve the balance after payments for the 100th and 180th
C use the u. s rules to solve final payment

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
