Verified Answer :

%increase = (increase / original number ) x100
increase = 3,24 - 2?85 = 0,39
the rate is 39%

The increase in percentage will be "39%".

According to the question,

Average price,

  • $2.85

Increase,

  • $3.24

As we know, the formula

→ \(Percentage \ increase = \frac{Increase}{Original \ number}\times 100\)

then,

→ \(Percentage \ increase = 3.24-2.85\)

                                   \(= 0.39\)

                                   \(= 39\) (%)

Thus the response above is appropriate.
