Question

1. A firm pays $1.75 for each copy of a magazine and sells each one for $2.50. There is a fixed monthly cost of $40 for printing the publication. If the firm wants to make $550 dollars next month, how many magazines do they have to sell?

Answer 1

For x magazines, we need

x(2.50-1.75) + 40.00 >= 550.00
x >= 680

Answer 2

oops, the $40 is a cost, not a profit

x(2.50-1.75) - 40.00 >= 550.00
x >= 754
