Madeline wants to plant 20 flowers in her garden. She assumes that about half of the seeds she plants will die before they bloom. However, the flower shop only sells packs of seeds with 25 seeds per pack. Each pack is $5. How much will Madeline spend on seeds to plant 20 flowers? Give me reasons, before answering the question
Madeline needs to buy 2 * 20 = 40 seeds to make sure that she will have 20 flowers. Thus, Madeline will need to buy 2 packs of flowers to have at least 40 seeds. Thus, Madeline will spend 2 * 5 = $10 on seeds. So the final answer is 10.
