n is for how many increments of $10 price increases.
PRICE         QTY SOLD           REVENUE
  140          50                140*50
 140+1*10     50+1*5             (140+1*10)(50+1*5)
 140+2*10     50+2*5             (140+2*10)(50+2*5)
 .
 .
 140+10n      50+5n            (140+10n)(50+5n)

If a revenue equation is what you want, then R=%28140%2B10n%29%2850%2B5n%29.






The description seems a little strange. Increase the price, and the monthly sales increases?
