The formula p=nc-e gives the profit p when a number of items n are each sold at a cost c and expenses e are subtracted. if p=5700, n=4000, and e=900. what is the value of c?

1.65

You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900

add 900 to both sides and you get

6600 = 4000c

divide both sides by 4000 and you get

1.65 = c

so the answer is 1.65
