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 = 3750, n = 3000 and e = 900, what is the value of c?

3750 = 3000c - 900

Add 900 to both sides, then divide both sides by 3000.

To find the value of c in the equation p = nc - e when p, n, and e are known, we can rearrange the equation to solve for c.

The given equation is:

p = nc - e

We are given the following values:

p = 3750
n = 3000
e = 900

Substituting the given values into the equation, we have:

3750 = 3000c - 900

To find the value of c, we need to isolate it on one side of the equation. Let's rearrange the equation:

3750 + 900 = 3000c

4650 = 3000c

Next, divide both sides of the equation by 3000 to solve for c:

c = 4650 / 3000

Simplifying the division gives us:

c = 1.55

So, the value of c is 1.55.
