Answer:
The correct answer is y = 0.550 × x + 75.
Step-by-step explanation:
The slope intercept form of a straight line is given by y = m × x + c, where m is the slope of the line; a and y are the two variables and c is the constant.
Let the total number of tickets sold by me is x and my the total money I make by selling tickets is $y.
For signing up to sell tickets, I receive a fixed payment of $75. Thus, this is my fixed income and is not dependent on how much tickets I sell. Thus c = 75.
For every ticket I sell, I get a $0.550 per ticket. Thus total income by selling x number of tickets is given by 0.550 × x. This is my variable income and depends on how many tickets I sell (more I sell, implies more I earn and vice versa).
Thus the total money made by me or rather my total income (y) is given by summing up my variable income and fixed income.
Therefore, y = 0.550 × x + 75.
