Answer:
5!
Explanation:
Looking at the first one, you have three watermelons. 36/3 is 12, so one watermelon is worth 12!
With the second one, you subtract 12 from 28 to get 16. Since there are two (peaches?), you divide 16 by two to get the peaches worth, which is 8.
That leaves you with the last one. I used the simple "8 - __ = 3", which got me the answer, 5.
I hope this helped!!
