Problem
Ali goes running Monday, Wednesday, and Friday of each week. Each Monday he runs 3.5 miles, each Wednesday he runs 5.75 miles, and each Friday he runs 7.5 miles. How many total miles does he run in 6 weeks? $?$
Solution
Step 1 ：Calculate the total miles Ali runs in one week: \(3.5 + 5.75 + 7.5 = 16.75\)
Step 2 ：Multiply the total miles in one week by 6 to find the total miles in 6 weeks: \(16.75 \times 6 = 100.5\)
Step 3 ：\(\boxed{100.5}\)
