The price of a shirt is reduced from $27 to $20. What percentage of the cost is the tip?

Step-by-step explanation:

Finding the percentage of the cost that is the tip means finding the percentage of the reduction or fall in price on the initial price.

The initial price of the shirt is $27

There was a reduction in price from $27 to $20. Reduction in price is determined by subtracting the new price from the original price. Therefore

Reduction in price (tip) = 27 - 20 = 7

To determine the percentage of the cost that is the tip, we will divide the tip by the initial cost and multiply by 100. It becomes

7/127 * 100

= 25.93%
