# If Tom sells 500 sandwiches for $7 and has an average cost of $5, what is his profit?

**Solution:**

Total number of sandwiches = 500

Selling price of each sandwich = $7

Total selling price = 7(500)

Total selling price = $3500

Cost price of each sandwich = $5

Total cost price = 5(500)

Total cost price = $2500

Profit = selling price - cost price

= 3500 - 2500

= 1000

Therefore, the profit on selling 500 sandwiches is $1000.

## If Tom sells 500 sandwiches for $7 and has an average cost of $5, what is his profit?

**Summary:**

If Tom sells 500 sandwiches for $7 each and has an average cost of $5 each, his profit is $1000.

**Example:**

If Sai sells 20 apples for $5 each and has an average cost of $2 each, what is his profit?

**Solution:**

Total number of apples = 20

Selling price of 20 apples = 20(5) = 100

Cost price of 20 apples = 20(2) = 40

Profit = selling price - cost price

Profit = 100 - 40

= 60

Therefore, his profit on selling 20 apples is $60.

**Summary:**

If Sai sells 20 apples for $5 each and has an average cost of $2 each, his profit is $60.
