Mark collects money for the homeless. He visits 20 households a day for 5 days and half of those households give him a pair of 20s. How much did he collect? Give me reasons, before answering the question
He got money from 20 / 2 = 10 households per day. So that means he got money from 10 * 5 = 50 households. Each of those houses gave 20 * 2 = $40. So he raised 40 * 50 = $2000. So the final answer is 2000.
