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

Question

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?

Answer 1

14
Each triple sells for 2$ less. 32 smoothies should have earned 64$. He only earned 52$, so 6 times the triple smoothie was sold = 18 smoothies. That means 14 smoothies were sold for 2$
