Roxy has 7 flowering plants in her garden. She has twice as many fruiting plants as her flowering plants. On Saturday, she goes to the nursery and buys 3 flowering plants and 2 fruiting plants. On Sunday, she gives away 1 flowering plant and 4 fruiting plants to her neighbor, Ronny.  How many plants are remaining in her garden? Give me reasons, before answering the question
Roxy’s flowering plant count is 7. Her fruiting plant count is 7 x 2 = 14. On Saturday, her flowering plant count is 7 + 3 = 10. On Saturday, her fruiting plant count is 14 + 2 = 16. On Sunday, her flowering plant count is 10 - 1 = 9. On Sunday, her fruiting plant count is 16 - 4 = 12. Roxy’s remaining plant count in her garden is 9 + 12 = 21. So the final answer is 21.
