Answer:the percent of increase in price is 7.69%
Step-by-step explanation:
The yearbook was sold for $26 at the beginning of the year. This means that the initial price of the year book was $26.
The price has increased to $28. The amount by which it was increased would be the current price - the initial price. It becomes
28 - 26 = $2
The percent of increase in price would be
Increase/initial price × 100
It becomes
2/26 × 100 = 7.69%
