Answer:
2000 units
Step-by-step explanation:
u = units sold
p = selling price
c = unit cost
Revenue = u × p
Costs = fixed costs + (c × u)
Profit = revenue - costs
Revenue = 10 × u
Revenue = 10u
Costs = 10000 + (5 × u)
Costs = 10000 + 5u
Breakeven means profits = 0:
Profits = 10u - (10000 + 5u) = 0
10u - 10000 - 5u = 0
5u - 10000 = 0
5u = 10000
u = 2000
