The next day, she doubled the previous day's sales. On the third day, she sold only 10% of the tulips sold on the second day and 16 roses. The price of one tulip is $2 and one rose is $3. How much did Maria earn over these three days?
Step-by-step reasoning process: On the second day, Maria sold 30 * 2 = 60 tulips. She also sold 20 * 2 = 40 roses the second day. On the third day, Maria sold only 10 / 100 * 60 = 6 tulips. Over these three days Maria sold 30 + 60 + 6 = 96 tulips. She also sold 20 + 40 + 16 = 76 roses. So on the tulips Maria earned 96 * 2 = $192. And on roses Maria earned 76 * 3 = $228. In total, over these three days, Maria has earned 192 + 228 = $420.
