3. In order to break even you must

sell 56 candy bars.

4. The minimum number of candy bars you must sell in order to start making a positive profit is 55.6 candy bars .

Step-by-step explanation:

equation: 140+1.50x-4x

140: startup fee

x: (amount) of candy bars

140 + 1.50 × 40 -  4 × 40

= 40

plug in 40 for both x's that are in the original equation. solve it out, and you get 40.

140 + 1.50 × 100 - 4 × 100

= -110

same thing as the part above, but plugging in 100 instead.

now to make the profit and the money you earn even, you have to find what number for x, makes the equation equal to 0.

140 + 1.50x - 4x = 0

after doing that, you solve for x

140 + 1.50x - 4x = 0

subtract 140 from each sides

1.50x - 4x = -140

now subtract 1.50 from 4

-2.5x = -140

now divide -2.5 from both sides which gives the

x = 56

which means that to make it even, you need to sell 56 candy bars

same as above, you solve for x but make the equation equal to 1

140 + 1.50x - 4x = 1

after solving, you get 55.6 candy bars
