150. 

You can get this answer by looking at the top right corner. It is that point.

Answer with explanation:

The given regression line in the scatterplot shows the number of bags of popcorn sold when x movie tickets are sold is ,

   y= 0.6 x + 10

Number of Bags of Popcorn sold = 100 bags

That is, y=100

100=0.6 x +10

100-10=0.6 x

0.6 x=90

[tex]x=\frac{90}{0.6}\\\\x=\frac{900}{6}\\\\x=150[/tex]

→→Number of movie ticket Sold = 150 tickets

Option C: 150
