Answer:
$296.64
Step-by-step explanation:
First, multiply 18.54 with 25.
18.54 x 25 = 463.5
Nine of the members have already paid for the cost. Multiply 18.54 with 9, and subtract the amount gotten from the total.
18.54 x 9 = 166.86
463.5 - 166.86 = 296.64
$296.64 still needs to be collected from the members who have not bought a shirt yet

The equation of the line of the best fit on the scatter plot is y = 150x + 598
<h3>How to determine the equation of the line of best fit?</h3>
From the line in the scatter plot, we have the following points
(x,y) = (3,1048) and (6,1498)
The equation is then calculated using:
![y = \frac{y_2 -y_1}{x_2 -x_1} *(x - x_1) + y_2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D%20%2A%28x%20-%20x_1%29%20%2B%20y_2)
The equation becomes
![y = \frac{1498 -1048}{6 - 3} *(x - 3) + 1048](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1498%20-1048%7D%7B6%20-%203%7D%20%2A%28x%20-%203%29%20%2B%201048)
Evaluate
y = 150 *(x - 3) + 1048
Expand the bracket
y = 150x - 450 + 1048
Evaluate the sum
y = 150x + 598
Hence, the equation of the line of the best fit is y = 150x + 598
