Answer:
(-86)
Step-by-step explanation:

You need to look at the question again, and notice the words "... did you ...".
From those words, it's clear that the question comes AFTER you have solved
several equations, and now, this question is asking you how you solved them.
The only way for YOU to answer this question is to solve the equations first.
And if you want someone ELSE to tell the math concepts and principles that
are used to solve them, then you have to show him what the equations are.
First you add up the number of coins in total so:
16+28+32+4
which equals: 80
Then to find 15% you have to do this:
80 divided by 100 then multiply by 15 which is 12.
The answer is 12.
