Answer 2

Given: The price of a sandwich decreases from $6 to $4.

To find: The percent decrease in the price of the sandwich.

Solution:

• The decrease in the price of the sandwich is calculated as,

        $6 - 4 = 2$

• The percent decrease in the price of the sandwich is calculated using the formula,

        $(percent)_{decrease} = \frac{d}{p} * 100$

• Here, d is the decrease in the price, p is the original price and 100 is multiplied since the percentage is being found out.
• On replacing the terms with the values given in the question,

        $(percent)_{decrease} = \frac{2}{6} * 100$

                                   $= 33.33%$

Therefore, the percent decrease in the price of the sandwich is 33.33%.
