A store manager bought c calculators for $8. All but four were sold for $10 each. The remaining four calculators were not sold. Find the store's profit, in simplified form, in term of c.

Well, let's do some math, or as I like to call it, "fun with numbers."

The store manager bought c calculators for $8 each, so the total cost would be 8c dollars.

Now, all but four calculators were sold for $10 each. That means the number of calculators sold is c - 4.

The profit on each calculator sold is $10 - $8 = $2.

So, the profit from selling c - 4 calculators is (c - 4) * $2.

But wait, there are still four unsold calculators. The store manager didn't make any profit from these, so we should subtract their cost.

The cost of the unsold calculators is 4 * $8 = $32.

Now, to find the profit, we subtract the cost of the unsold calculators from the profit made on the sold calculators:

Profit = (c - 4) * $2 - $32

And there you have it, the store's profit, in simplified form, in terms of c, is (c - 4) * $2 - $32.

Let's break down the problem step by step:

1. The store manager bought c calculators for $8 each. So, the total cost for c calculators is 8c dollars.

2. All but four calculators were sold for $10 each. Let's find the number of calculators sold: c - 4.

3. The total revenue from selling these calculators is (c - 4) * $10 = 10(c - 4) dollars.

4. The remaining four calculators were not sold, so there is no revenue from them.

5. The store's profit can be calculated by subtracting the cost from the revenue: profit = revenue - cost.

Profit = 10(c - 4) - 8c

6. Simplifying the expression, we get:

Profit = 10c - 40 - 8c

Simplifying further:

Profit = 2c - 40.

So, the store's profit in simplified form, in terms of c, is 2c - 40.

To find the store's profit, we need to determine the cost of the calculators and the revenue from selling them.

Let's start by finding the cost of the calculators. The store manager bought c calculators for $8 each, so the total cost would be $8 multiplied by c, which can be written as 8c.

Next, we will determine the revenue from selling the calculators. All but four were sold for $10 each, so the number of calculators sold is c - 4. Therefore, the revenue from selling them is (c - 4) multiplied by $10, which can be written as 10(c - 4).

The profit is calculated by subtracting the cost from the revenue. Thus, the store's profit is given by:
Profit = Revenue - Cost
Profit = 10(c - 4) - 8c

Now, we can simplify the expression:
Profit = 10c - 40 - 8c
Profit = 2c - 40

Therefore, the store's profit, in simplified form, in terms of c is 2c - 40.

(c-4)*10 - 8c = 2c -40
