Answer:
Option C
63
Step-by-step explanation:
Using the given equation y = 0.338x − 1.387 and since you're given the the number of commercials, you substitute this for y hence
20= 0.338x − 1.3877
20+1.3877=0.338x
0.338x=21.3877
x=21.3877/0.338=63.27514793
Rounding off, x=63. \the question says x represents the minutes spent hence the answer is 63
