Answer:
$866.13
Step-by-step explanation:
to get an average, you add up all the factors then divide them by how many there are. I added 500 12 times to 1250 12 times to 1150 3 times and 600 4 times.
aka (500*12)+(1250*12)+1150+1150+1150+600+600+600
then i divided by 31 because 12+12+3+4=31. giving the average $866.13.
