Heads of lettuce that are normally priced at $0.78 each are now being offered for a special price of 3 for $2. If Mr. Graboski wants to buy 6 heads of lettuce, how much will he save if he buys them at the sale price instead of the regular price?

If Mr. Graboski buys 6 heads of lettuce at the regular price, he pays 6 * 0.78 = 4.68$. But if a special price is proposed, he pays $2 for each 3 heads, so he spends 2 * 2 = 4$ as he needs 6 heads. So, Mr. Graboski saves 4.68 - 4 = 0.68$.
