Let's break down the puzzle step-by-step to find the values of each fruit.

First equation (3 apples):

$$\text{apple}+\text{apple}+\text{apple}=30$$

This implies that each apple is worth 10.

$$\text{apple}=10$$

Second equation (1 apple and 2 bunches of bananas):

$$10+\text{bananas}+\text{bananas}=18$$

Subtracting 10 from both sides:

$$2\times \text{bananas}=8$$

So, each bunch of bananas is worth 4.

$$\text{bananas}=4$$

Third equation (1 bunch of bananas and 2 coconut halves):

$$4-\text{coconuts}=2$$

Subtracting 4 from both sides:

$$\text{coconuts}=2$$

This means that each coconut half is worth 1 (since there are two halves in the picture).

Final equation: The last line shows one coconut half, one apple, and one bunch of bananas:

$$\text{coconut half}+\text{apple}+\text{bananas}=??$$

Substituting the values we found:

$$1+10+4=15$$

The answer is 15.
