To find the cost of this dish, we first have to determine how much the price will increase. We do that by multiplying the original price by the percentage it is going to increase by, which is 20%.  In order to carry out this operation, we need to convert the percentage to a decimal.  To do this, we simply divide 20 by 100 (since that is the denominator of every percentage value).
Then, multiply 0.2 by 8.
0.2 • 8 = 1.6
Then, because we're looking for the new price, we have to add the increase in amount to the original.
8 + 1.6 = 9.6
Since we are referring to money, we will add a zero behind the 6.
$9.60
