Daisy's Flower Shop sold 45 daisies on its first day. On their second day, they sold 20 more flowers than they did on their first day. On the third day, they sold 10 less than twice the flowers that were sold than on the second day. If the flower shop sold a total of 350 daisies for 4 days, how many daisies were sold on the 4th day?
Thoughts? Step-by-step reasoning:
The flower shop sold 45 + 20 = 65 daisies on the second day. Twice the number of flowers on the second day is 65 x 2 = 130. So, the flower shop sold 130 - 10 = 120 daisies on the third day. The total daisies sold for 3 days was 45 + 65 + 120 = 230. Therefore, 350 - 230 = 120 daisies were sold on the 4th day.
Thus, the answer is 120.
