Answer:
Explanation:
<u>1. Model:</u>
i) Profit = Revenue - Cost
ii) Revenue = price × number of items
iv) Cost = variable cost + fixed expense
<u>2. Solution</u>
i) Revenue = $ 57 / item × 419 items
ii) Cost = $ 23 / item × 419 items + $5,984
iii) Profit = $ 57×419 - ($23×419 + $5,985)
Profit = $ 23,883 - ($ 9637 + $ 5,984) = $ 23,883 - $ 15,621
Profit = $ 8,262 ← answer
