The equation yequals=10.210.2xplus+6.66.6
estimates the amount that businesses will spend, in billions of dollars, on a certain business technology, where x is the number of years after 20012001.
For what years will the spending be more than $2727 billion?

My guess is that you did a copy-and-paste from an online assessment, and didn't note that something caused duplication. I will guess that the exercise was actually as follows:
. . . . .\(\displaystyle \mbox{The equation }\, y\, =\, 10.2x\, +\, 6.6\, \mbox{ estimates the amount, in billions of}\)
. . . . .\(\displaystyle \mbox{dollars, on a certain business technology, where }\, x\, \mbox{ is the number of years}\)
. . . . .\(\displaystyle \mbox{after 2001. For what years will the spending be more than \$27 billion?}\)
If I have guessed incorrectly, please reply with corrections. If I have guessed rightly, please reply explaining where you are stuck. You've been given an equation where "y" is "billions of dollars" and "x" is years after 2001. You've been given an inequality statement; namely, that "billions of dollars" will be "greater than 27". You've plugged the given value into the given variable in the given equation (or, if you're savvy, the corresponding inequality), solved for the corresponding value of x, added the value to the initial value to get the year, and... then what?
Please be complete. Thank you!
