It was going to be another really hot day, but Ted needed a new pair of cool sunnies* before he could hit the surf. He needed another $52 to buy the ones he wanted.

Ted decided to sell home-made smoothies at his gate: $2 each, or three for $4. He had the $52 after selling 32 smoothies, stopped work and headed off to the beach.

How many smoothies had been sold at the $2 price?

* sunnies = sunglasses in New Zealand & Australia


[14 @ $2 = $28; 18 @ 3 for $4 = $24]

If he had sold them all at $2, he would have earned $64. The $12 difference is the discount he gave to six people buying 3 for $4.

So 18 were sold at the discount price - the other 14 were sold individually.
