Please answer the following question by reasoning step-by-step.
You start a business selling charm bracelets. You spend $1 on the string for each bracelet and $3 on beads for each bracelet. You sell the bracelets for $6 each. If you sell 25 bracelets, how much profit will you make?

50
It costs $1 + $3 = $4 to make each bracelet.

Your total cost is 25 * $4 = $100.

Total revenue is 25 * $6 = $150.

Total profit is $150 - $100 = $50.

.

The answer is 50
