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

Solution:
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.
