Answer:
Total production costs when 105,000 toys are produced = $393,275
Explanation:
Provided that total cost of manufacturing 90,000 toys = $370,000
Out of which variable cost = $140,000
That means fixed cost = $370,000 - $140,000 = $230,000
Now variable cost per unit = $140,000/90,000 units = $1.555
Therefore cost of producing 105,000 toys with same relevant range = $1.555 X 105,000 = $163,275 = Variable Cost
Note: Fixed cost will remain same as the range of production level is same.
Therefore fixed cost for producing 105,000 units = $230,000
Therefore total cost = $163,275 + $230,000 = $393,275
