Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any
number of plates, x? 5 y = 44 y = 8.8 x On a coordinate plane, the x-axis is labeled number of plates and the y-axis is labeled total cost (in dollars). A line goes through points (2, 30) and (4, 40). On a coordinate plane, the x-axis is labeled number of plates and the y-axis is labeled total cost (in dollars). A line goes through points (10, 1) and (60, 7).

3. The first one represents Dale's commission
Explanation:
1. The composition of the function
means that you first apply the function g(x) and then f(x) on the output of g(x).
That is:
- f(x) = 0.05x
- g(x) = x - 3000
2. The composition of the function
means that you first apply the function f(x) and then g(x) on the output of f(x).
That is:
3. Which one represents Dale's commission
To calculate Dales's commision you must subtract $3,000 from the sales, to find the sales over $3000. That is: x - 3,000, which is the function g(x).
Therefore, you first use g(x).
Then, you must multiply the output of g(x) by 0.05 to find the 5% of the sales over $3,000. That is: 0.05(g((x)) = 0.05(x - 3000) = 0.05x - 150.
Therefore, the composition that represents Dale's commission is the first one:
