Company Zula sells only chairs and tables. In 2008, the average price of tables sold by Zula was 10% higher than the average price of chairs. In 2008, Zula also sold 20% fewer tables than chairs. What percent of its revenue in 2008 did company Zula derive from its sales of tables?


How I solved...(?)

1) I used easy numbers. "The avg price of tables sold by Zula was 10% higher than the avg price of chairs". So avg price of tables was $11 and avg price of chairs was $10.

2) "Zula also sold 20% fewer tables than chairs." So, use easy numbers again... Lets say Zula sold 8 tables and 10 chairs.

3) P*Q = revenue
Tables: $11*8=$88
Chairs: $10*10=$100

So answer is, $88/$188 <--($100+$88 = Total Revenue). Is my method correct? Thanks!
