 <translate> First convert the bill amount to cents: $26 * 100 cents / dollar = 2600 cents. Then multiply that amount by 5% to find the amount Gina normally tips: 2600 cents * 5% = 130 cents. Then multiply the bill amount by 20% to find the amount of a good tip: 2600 cents * 20% = 520 cents. Then subtract the good tip amount from the bad tip amount to find how much more Gina needs to tip: 520 cents - 130 cents = 390 cents. The answer: 390. <yor> Lákọ̀ọ́kọ́ ná, kó o yí iye tí owó náà jẹ́ pa dà sí cents: $26 * 100 cents/dollar = 2600 cents.
