Give the step-by-step reasoning process and then the final answer. Scott runs 3 miles every Monday through Wednesday. Then he runs twice as far he ran on Monday every Thursday and Friday. How many miles will he run in a month with 4 weeks?
User
Scott runs 3 x 2 = 6 miles every Thursday and Friday. The total miles run by Scott for a week from Monday through Wednesday is 3 x 3 = 9 miles. The total miles run by Scott for a week from Thursday to Friday is 6 x 2 = 12 miles. So, in a week, Scott runs a total of 9 + 12 = 21 miles. Thus, he runs a total of 21 x 4 = 84 miles in a month.
The final answer: 84.
