Answer:
$3,000
Step-by-step explanation:
To find his average monthly pay, you have to find the total amount that Willian received in a year by multiplying his monthly salary as a teacher for 10 months and his salary as a barista for 2 months and adding up these numbers. Then, you have to divide the total amount he earned by 12 that is the number of months in a year:
($3,200*10)+($2,000*2)= $32,000+4,000=36,000
$36,000/12=$3,000
According to this, his average monthly pay for the 12 months was $3,000.
