This one is a bit hard to figure out. The question "How many coins?" is problematic since coins can be 0.01, 0.05, 0.10, .025, 0.50 or 1.00. Historically there were other denominations as well. Do you mean how many dollars?
Additionally, you have stuff in different shapes. Does the circle represent a whole so it is 50% of the value of a red bar minus 4? Or is it just a plate or tray? If it is a pie, then what is the rectangle? Are those fractions regardless fo the shape and if so, why not use the same shape for both?
Im guessing that the 16 dollars one is the green and yellow Sunday cup one with the cherry in it. The bottom 2 togeather add up to 11 so it cant be either of those. . .
