PART A:
Given the 15% return from selling accessories and services on computer product sales, the equation would be:
y = 0.15x + 2500.
To reach a total of $5000 for the year, the sales from computer products must be (5000 - 2500) / 0.15, which is about $16,666.67.
PART B:
The slope of the equation is 0.15, representing the 15% return on computer product sales, and the y-intercept is 2500, the amount already earned in January and February.
PART C:
A graph would be a straight line with a slope of 0.15 and y-intercept of 2500.
This would be "Graph III".
This line shows the expected accessory and service sales based on computer product sales.
The point where it hits y = 5000 represents the computer sales target.
