Answer:
We'll use the variable x to represent last year's price. First, we have to set up an equation:
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:
Last year's price was $12.50.

Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 5 , x = 21
k = yx = 5 × 21 = 105
y =
← equation of variation
When x = 10, then
y =
= 10.5
