A)
50 ≤ 5.75p - 4.75p
Eliminate
B)
50 ≥ 5.75p - 4.75p
C)
50 ≤ 5.75p - 3.25p
D)
p ≤ 5.75(50) - 4.75p

please disregard eliminate

phi · Answer

it would be great if you could figure this out, because it is "thinking"  and thinking is good.

You should let  "p"  stand for the number of pies

profit is the money coming in minus the money spent to make the pie

how much money "comes in" ?
how much money does he spend ?
can you answer those questions ?

I think the answer is a but wasn't sure

phi · Answer

they want the profit to be bigger than 50
so you definitely want an equation with
50 ≤ profit  
which is a way to say, "profit is greater than or equal to 50"

now you need to figure out which of the choices  gives you the correct expression for the profit.

to do that you should answer
how much money "comes in" ?
how much money does he spend ?

I still think it is a because the sale price vs the deduction of the cost to produce.

phi · Answer
