Sarah creates bouquets of flowers with an equal number of flowers in each bouquet. She had 240 flowers when she started, with 128 flowers remaining after she created 7 bouquets. This situation can be represented by the linear equation y=24 - 1x where y is the total number of flowers, and x is the number of bouquets created. How many flowers are in each bouquet? (The variables can only be positive numbers.)
