I've always found these "What do *you* think I meant?" puzzles annoying. Often the authors make arbitrary assumptions that cannot be logically defended, but nevertheless you're expected to replicate their flawed logic to match their result. In this case, ok, maybe two yellow flowers are supposed to be twice as much as a single yellow flower. I guess I can buy that. But how about the blue flowers with 4 vs. 5 petals? Is a 4-petal flower really worth 80% of a 5-petal flower? If so, then that assigns 100% of the value to the petals. Why? What if 50% of the value lies in the center? And what if some of the value lies in the leaf or stem? And if the answer is "Well, that's too complicated, counting the petals is simple and clear", then my response is "When was the last time you saw flowers for sale whose price was dependent on the number of petals? Clearly it's simpler to value them all the same." Also, presumably multiplication is meant to group more tightly than addition in the bottom row, but who knows, they may think all arithmetic should proceed left-to-right regardless of standard operator precedence.

FYI -- Better fire that math teacher and Professor Puzzler; maxima trivially solves this puzzle (follow link to jpeg of the equation set) and it has a unique answer.
"Brain-splitting equation that even a MATHS TEACHER can't solve has the entire Internet baffled... So do YOU know the answer?"

"A simple logic and maths puzzle has sparked debate on Facebook after thousands of people have debated over the answer. The puzzle, which replaces numbers with flowers, has caught thousands of people out. A maths teacher who solves logic puzzles online and goes by the name of 'Professor Puzzler' even refused to solve it, saying the problem had no answer."
