Explanation

Total earnings = (10 months * 3200) + (2 months * 2000) = 32000 + 4000 = 36000. Average monthly pay = 36000 / 12 = 3000.

Using the weighted average method, the total earnings for 10 months at $3,200 is $32,000. Earnings for 2 months as a barista at $2,000 is $4,000. The total earnings for the year are \$36,000, and dividing this by 12 months gives an average monthly pay of \$3,000.
