Step-by-step explanation:
For the food booths, we can create an equation based on the y = mx + b equation. Since they are charging 8 dollars per day and they last for d days, then the slope is 8 or the rate is 8d. Since they also charge us 175 dollars which is a one time fee, it is the y-intercept. So the equation is
y = 8d + 175.
Since there are 18 food booths, then we can multiply the equation by 18.
y = 18(8d + 175)
y = 144d + 3150
For the game booth, we do the same thing. Since they charge us 7 dollars per day and the fair lasts for d days, then the rate is 7d. Since they also charge us 50 dollars as a one time fee, then it is the y-intercept. The equation for the game booth is:
y = 7d + 50
Since there are 23 game booths, multiply the equation by 23.
y = 23(7d + 50)
y = 161d + 1150
Now add them up to know how much they are being paid.
y = 305d + 4300
Hope this helps.
