Question

ok this is a really complicated deal so here is the scenario:
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?

Answer 1

Step 1: Set up the variables. Let x = the number of units
y = the cost/income (expense/revenue) in dollars

Answer 2

Step 2: Write cost (expense) and income (revenue) equations. Cost Equation:
total cost = fixed cost + (cost to make each unit) · (# of units)
y =

Income Equation:
total income =
y =

Answer 3

Step 3: Solve the system of equations using substitution.

Answer 4

Step 4: State the break-even point.
then they want me to graph it

Answer 5

Step 4: State the break-Even Point.

and then I'm suppose to graph it............

Answer 6

I don't understand what the heck we are doing and I am so confused..........
anyone got a clue? @GoldEverything @jim_thompson5910

Answer 7

what do you need help with

Answer 8

ok well I don't understand how to even start step 1

Answer 9

x = ?
y = 300/500 (80,000/1)
did i do it right?

Answer 10

i think so

Answer 11

it doesn't make sense right?

Answer 12

their just asking me to do a bunch of random pellet which really pisses me off cuz they didn't explain to me how the heck i am suppose to do this, and i have a worksheet with like 30 problems like this and im just so confused right now :(
