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?
It costs $1 + $3 = $<T>add(1, 3)=4 to make each bracelet.
Your total cost is 25 * $4 = $<T>multiply(25, 4)=100
Total revenue is 25 * $6 = $<T>multiply(25, 6)=150
Total profit is $150 - $100 = $<T>subtract(150, 100)=50
