The increase in percentage will be "39%".

According to the question,

Average price,

  • $2.85

Increase,

  • $3.24

As we know, the formula

→ [tex]Percentage \ increase = \frac{Increase}{Original \ number}\times 100[/tex]

then,

→ [tex]Percentage \ increase = 3.24-2.85[/tex]

                                   [tex]= 0.39[/tex]

                                   [tex]= 39[/tex] (%)

Thus the response above is appropriate.
