Box seats for a ball game cost $b each and general admission seats cost$g each. If 10,000 seats are sold, and x of the seats are box seats, which expression gives the fraction of money made on seat sales that came from box seats?

A. $$\frac{bx}{bx+(10,000-x)g}$$

B. $$1+(10,000-x)g$$

C. $$\frac{bx}{10,000}$$

D. $$\frac{b}{b+g}$$

E. $$\frac{x}{10,000}$$

Number of box seats sold = x
Cost of total box seats sold = bx
Number of general seats sold = 10,000 - x
Cost of total general seats sold = (10,000 - x)g
Fraction of money from box seat sales = $$\frac{bx}{bx+(10,000-x)g}$$

D. $$\frac{b}{b+g}$$

E. $$\frac{x}{10,000}$$

If x seats are box seats, then (10,000 - x) seats are general admissions seats.

Thus, the money made on box seats was bx, and the total money made on all 10,000 seats was bx + g(10,000 - x).

Thus, the fraction of the money made on seat sales that came from box seats was:

bx/[bx + g(10,000 - x)]

In the question stem, X is the total number of box seats OR X is the number of seats that were sold from total box seats????

It is so unclear from the wording

Should not the question be telling from THOSE 10,000 seats x are box seats ....It seems like they are telling the total number of box seats, which may give different equation and meaning

Re: Box seats for a ball game cost $b each and general admission seats cos [#permalink] ### Show Tags 22 Oct 2017, 12:51 I am pretty sure I got this problem wrong. Part of my issues on the GMAT is that I rush to answer these questions and often don't read the question correctly. _________________ I'd love to hear any feedback or ways to improve my problem solving. I make a lot of silly mistakes. If you've had luck improving on stupid mistakes, I'd love to hear how you did it. Also, I appreciate any kudos.
