The new price of the guitar would be $464.00

Step-by-step explanation:

The music store increased the price of guitar by = 45%

First we calculate 45% of the 320 and then add it to the original price.

The new price of the guitar = 320 + ( 45% × 320 )

                                              = 320 + ( 0.45 × 320 )

                                              = 320 + 144

                                              = $464

The new price of the guitar would be $464.00
