Answer:
$150 billion in total will be spent on both Internet Advertising and TV Advertising.
$0.6 million more will be spent on Internet Advertising than TV.
Let TV Advertising expenses be x.
Expression will be;
x + (x + 600,000) = 150,000,000,000
2x = 150,000,000,000 - 600,000
x = (150,000,000,000 - 600,000) / 2
TV Advertising = $74,999,700,000
Internet Advertising
= TV Advertising + 0.6 million
= 74,999,700,000 + 600,000
= $75,000,300,000
