A restaurant owner is told, to keep his license, the ratio of his liquor sales to food sales cannot exceed 2.5:1. If the restaurant has $50,000 in food sales, how much liquor slaes can it have?

Is this correct?:

2.5___50000

--- =-------

1______x

therefore:2.5x=50000

x=$20,000 in liquor sales?!?
