The yearbook was sold for $26 at the beginning of the year.since the price has increased to $28.what was the percent of increase in price (round to the hundredths place

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%

The two graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs. 

The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.

The final graph represents a quadratic function rising on both ends. 

Therefore, option b and c are the correct answers
