Answer:
$ 1250
Step-by-step explanation:
output = 50 units per day
average total cost = $ 60
total cost = output × average total cost =50 × 60 = $ 3000
total variable cost = output × average variable cost = 35 × 50 = $ 1750
total cost = total fixed cost + total variable cost
total fixed cost = total cost - total variable cost = $ 3000 - $ 1750 = $ 1250
Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
