From Businesses Intensify Pitch for 'Savviest Generation Ever' by Dave Carpenter © 2012 The Associated Press
Teenage Research Unlimited, a market research firm in Northbrook, Ill., projects that the 31.6 million Americans from ages 12-19 will spend $108 billion of their own money in 2000, along with $47 billion of their family's funds.
They also account for a disproportionately large share of consumer spending. Households with one or more teen-agers spend $10,000 more per year than those without any. And with parents working more than ever before, teens have assumed greater influence in household decision-making.
What is the central idea of this passage?
A) Market research firms are interested in what teen-angers have to say.
B) In families with working parents, teen-angers affect decision-making.
C) Teen-angers account for billions of dollars of consumer spending every year.
D) Households with teen-angers spend more than those without any teen-angers.
