I need help forming the equations, I don't want the answer, I just want assistance in finding the answer.

Variables have already been declared as the following

C = Cost
b = number of loaves baked
R = Revenue

enter image description here

EDIT: I thought the first equation should be C = 0.60b But that seems to be incorrect.

  • $\begingroup$ You forgot about the fixed cost of $80$ bucks just to rent the place even if you don't bake any bread. $\endgroup$ Commented Feb 13, 2014 at 21:26
  • $\begingroup$ So that means it should be C = 0.60b + 80, right? $\endgroup$

  • $\begingroup$ You are welcome. The leaving out of the $80$ was a minor oversight. In setting up equations, we need to think concretely (how much doe we spend) before turning to algebra. $\endgroup$ Commented Feb 13, 2014 at 22:10

In your edit you say that your firsts attempt to find the equation for the first question is $C = 0.60b$ here, you're thinking in the correct way but your forgetting to add the cost that doesn't depend on $b$

You should be fine with the second question

Look carefully at the sentences at (a) and try to explain $C=0.6b +80$. Similar for (b) $R=1.6b$. Can you write down a formula for the profit? How many loaves have to be sold to make it a profitable business?
