Wilma has a garden with 3 types of flowers. The garden has 6 rows, with 13 flowers in each row. Wilma has 12 yellow flowers, two times more green flowers, and the rest consist of red flowers. How many red flowers does Wilma have?
##Solution## The garden has space for 6 * 13 = <<6*13=78>>78 flowers in total.
Wilma has two times more green flowers than yellow flowers, which means she has 2 * 12 = <<2*12=24>>24 green flowers.
That leaves us with 78 - 24 - 12 = <<78-24-12=42>>42 red flowers in the garden.
