During the past year, a firm produces 250 tablet devices at an average variable cost of $40 and at an average fixed cost of $10. what were the firm's total costs during the year?

The total costs = Total variable costs + Total fixed costs

Given,

Average variable costs = $ 40

Average fixed cost = $ 10

Tablets produced during the year = 250

Total variable cost = Average variable costs * Tablets produced during the year

Total variable cost = 250 tablets * $ 40 = 10,000

Total fixed cost = Average fixed costs * Tablets produced during the year

Total fixed cost = 250 tablets * $ 10 = $ 2,500

Total costs = Total variable cost + Total fixed cost

Total costs = $ 10,000 + $ 2,500 = $ 12,500
