The total cost to produce 80 dolls is $1,200. If each doll costs $10 to produce, find the fixed costs.

$

Step-by-step explanation:

Total Cost = Fixed + Variable Cost

Variable Cost = $10 × 80 = $800

$1200 = Fixed Cost + $800

Fixed Cost = $1200 - $800

Fixed Cost = $400

A' = 103°

B' = 100°

C' = 80°

D' = 77°

Step-by-step explanation:

B' = 180 - 80 = 100°

C' = 80 because it is a corresponding to 80°

D' = 180 - 125 = 55, 180 - 48 - 55 = 77°

A' = 360 - 77 - 100 - 80 = 103°
