To find the relationship between them, lets do some algebra:
f(x) = (7/10)^x
g(x) = (7/10)^-x
if we do:
f(x) * g(x) = 1
due to exponents multiplying addition law, therefore, the relationship, gives:
f(x) = 1 / g(x)
So 32 dollars for 8 cookies.
To find the price of one item, you take the amount of items, and divide it by the price:
32 / 8 = 4 dollars for the price of 1 cookie.
