Explanation:
If y varies inversely as x, the two variables can be represented in an equation in the form
y
=
k
x
where
k
is some constant.
We are given that
y
=
5
when
x
=
6
. We can plug this into the above equation to find what
k
is:
5
=
k
6
30
=
k
Based on this we can create our equation:
y
=
30
x
And then find
x
when
y
=
2
:
2
=
30
x
2
x
=
30
x
=

First: Figure out the cost per candy bar currently by dividing 3.22 and 14
3.22 / 14 = 0.23
Second: Add in 0.15 to your total to solve for the prior cost of the candy
0.23+0.15 = $0.38
