A bar graph illustrates the number of customers visiting a store over four weeks. If Week 1 had 120 customers, Week 2 had 150, Week 3 had 180, and Week 4 had 200, what is the average number of customers per week?

Step 1: Write down the number of customers for each week: Week 1 = 120, Week 2 = 150, Week 3 = 180, Week 4 = 200.
Step 2: Add the number of customers from all four weeks together: 120 + 150 + 180 + 200.
Step 3: Calculate the total: 120 + 150 = 270, then 270 + 180 = 450, and finally 450 + 200 = 650.
Step 4: Count the number of weeks: There are 4 weeks.
Step 5: Divide the total number of customers (650) by the number of weeks (4): 650 ÷ 4.
Step 6: Calculate the average: 650 ÷ 4 = 162.5.
