Sunnies
Math brain teasers require computations to solve.
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

Posted by annie9698 on Oct 14, 2012 what if he sold 20 @ $2 =$ 40 and 9 @ 3 for 4 = $12 Or sold 22 @ $2 = $44 and 6 @ 3 for 4 = $8 I haven't done all the math but there may be other solutions too. |

Posted by Mad-Ade on Oct 25, 2012 he could have sold 16 at $3 = $48 and two at $2 = $4 with adds up to the $52 needed. There are numerous answers to this teaser. |
