I have a couple word problem equations if you will....

[whitman.57]

1.A carpenter used 30.7 feet of molding in three pieces to trim a garage door. If the longest piece was 2.3 feet longer than twice the length of each shorter piece, how long was the longest piece?



2.

Rich knows that his neighbor Jessi paid $40152.23, including sales tax, for a new car. If the sales tax rate is 8.3%, what is the cost of the car before the tax?

$ I got this for an answer but don't know why I am wrong!

Haven't quite seen your efforts. Haven't really seen a good question, either.

"A carpenter used 30.7 feet of molding in three pieces to trim a garage door. If the longest piece was 2.3 feet longer than twice the length of each shorter piece, how long was the longest piece? "

Are the shorter pieces the same length?

What was your answer?

don't know why I am wrong! - To know that, you need to share your work.
