Answer:
26 3/4 as a decimal would be 26.75
A maxm speed of 55 mph means that the speed has to be lexx than or equal to 55
x <= 55
The value of x from the given equation is 5/3
<h3>How to determine the value</h3>
Since the three points are collinear to U, they are on a straight line which equals 0
Then we have,
UM + UD = MD
5x+30 + 10x+20 = 3x+80
Collect like terms
5x + 10x + 50 = 3x + 80
15x - 3x = 80 - 50
12x = 30
x = 30/12 = 15/6 = 5/3
Thus, the value of x from the given equation is 5/3

Then, it would be 156 + 156*6.5 /100 = 156+10.14 = $166.14
