percentages

by Woozler » Mon Dec 13, 2010 10:23 am
A manufacturer produced x percent more video cameras in 1994 than in 1993, and y percent more video cameras in 1995 than in 1994. If the manufacturer produced 1000 video cameras in 1993, how many video cameras did the manufacturer produce in 1995?

(1) xy = 20
(2) x + y + (xy)/100 = 9.2
