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?

3000c - 900 = 3750

3000c = 4650
c = 4650/3000

or, more directly

c = (p+e)/n

To find the value of c, we can rearrange the formula p = nc - e to solve for c.

The formula can be rearranged as follows:
p + e = nc

Substituting the given values:
3750 + 900 = 3000c

Now we can solve for c.
4650 = 3000c

Dividing both sides of the equation by 3000:
c = 4650/3000 = 1.55

Therefore, the value of c is 1.55.

To find the value of c in the given formula, we can rearrange the formula and isolate c.

The formula is given as:
p = nc - e

Now, we need to rearrange it to solve for c:
p + e = nc
c = (p + e) / n

Substituting the given values:
p = 3750
n = 3000
e = 900

We can calculate the value of c using the formula:
c = (p + e) / n
c = (3750 + 900) / 3000
c = 4650 / 3000
c = 1.55

Therefore, the value of c is 1.55.
