Question

The equation y=10.5x estimates the amount that businesses will​ spend, in billions of​ dollars, on a certain business​ technology, where x is the number of years after 2004. For what years will the spending be more than ​$34 ​billion?

Answer 1

2007 and beyond.

Explanation:

y = 34 ==> y doesn't equal 34 billion as y is already measured in billions

Since y=10.5x:

34 = 10.5x ==> solve for x

x = 34 / 10.5 ==> divide both sides by 10.5

x = 3.2 ==> x is approximately 3.2 years

2004 + 3.2 = 2007.2

2007.2 rounded to the nearest year is 2007

Hence, businesses will spend more than $34 billion in the year 2007 and beyond.
