5(x-2)=10
5x-10=10
5x=20
5x/5=20/5
x=4
Here you go! :)
First identify how many want 7:00. 40 - 15 = 25
25/40 = 0.625
Thus, 62.5% wanted a 7:00 start time.
Looking at the graph, we'll notice that there is a local maximum at x=0 and it looks similar on both sides of the y axis, therefore making it symmetric around the y axis given the options
