Suppose your business makes high-grade PDAs, personal digital assistants. It costs you $80,000 a month for fixed costs, such as rent, employee salaries, and other essential items. Also, it costs $300 to make each PDA, called a unit. If you are able to sell each unit for $500, how many PDAs do you need to sell to break even?
Let x = the number of units
y = the cost/income (expense/revenue) in dollars
Cost Equation:
total cost = fixed cost + (cost to make each unit) • (# of units)
Income Equation:
total income
Please help me! I'm so confused

Well this should be basically easy as it can get once I give you this equation.

dtan5457 · Answer

80000+300x=500x

dtan5457 · Answer

Solve that for the # of pda

dtan5457 · Answer

Clear?

dtan5457 · Answer

Well I actually have to start my own work, so I'll finish it for you. You have 80000 as the fixed price+$300 per pda to make. To even that income you get $500 per pda.

80000+300x=500x

Subtract 300x

80000=200x

400 pda's to balance it out.
