We know that the price for 12 cans is $30. So we can set up an equation. Let c equal the price of one can.

12c=30

Now solve the equation for c, and multiply the value of c by 7.
Alternatively, you could multiply $30 by (7/12).
Just use a proportion:
12 cans/7cans = $30/$x
12/7 = 30/x
12x = 210
x = 210/12 = 17.50
