The answer should be J.15.
It is A. 0.05 represents one of his candies, and x represents how many of those, 0.10 represents the other candy while y represents how many of those candies. 1.00 is the total it should come to.
I believe the expression would be:
x+2
For example, if you have the odd number 3 as x, 3+2 would be 5, the next odd number.
Hope this helped!! xx
