Question 875325
let x represent the number of calculators

fixed costs = 650,000

variable cost = 47 each

C= 650,000+47x

Sales = 63x

To make a profit

sales > costs

63x>650,000+47x

63x-47x>650,000
16x>650,000

/16
x>650000/16

it has to sell more than 40625  to make a profit.

For break even
sales = cost
it will break even at 40625 calculators
