In a retail store, the average (arithmetic mean) sale for month $$M$$ was $$d$$ dollars. Was the average (arithmetic mean) sale for month $$J$$ at least $$20$$ percent higher than that for month $$M?$$

(1) For month $$M,$$ total revenue from sales was $$\3,500.$$
(2) For month $$J,$$ total revenue from sales was $$\6,000.$$
