<u>Function Models</u>
A company rents out food booths and game booths at the county fair.
For a food booth, the company charges a fixed fee of $175 and a variable fee of $10 per day. If d is the number of days, then the charges for a food booth are:
Cf = 175 + 10d
Similarly, the company charges $50 plus $9 per day for a game booth, thus the total charges are:
Cg = 50 + 9d
If all the booths are rented for the entire time, the total amount the company is paid for 17 food booths and 22 game booths is:
Ct = 17Cf + 22Cg
Substituting:
Ct = 17(175 + 10d) + 22(50 + 9d)
Operating:
Ct = 2975 + 170d + 1100 + 198d
Simplifying:
Ct = 4075 + 368d

Answer:
X+4
Step-by-step explanation:
X(3, -1) → x = 3, y = -1
x - no change
y:
calculate the distance between X and y = 1
1 - (-1) = 1 + 1 = 2
calculate the value of y in coordinates of X':
1 + 2 = 3
Answer: (3, 3)
Answer: 16.5%
Step-by-step explanation:
given data:
estimated circumfrence of the earth = 250,000 stadia.
Actual value = 46,620km
expected Value = 40,030.3km
solution:
percentage error = actual value – expected value/ expected value * 100
= 46,620 – 40,030.3 / 40,030.3 * 100
= 6589.7 / 40,030.3 * 100
= 0.16462 * 100
= 16.5%
percentage error is 16.5%
