Jed owns a music store and is taking inventory to prepare for a new order. He has organized the count of instruments in the table below. Help Jed analyze his store and place an upcoming order.

Answer:
String instruments = 13%
Percussion Instruments = 18%
Wind Instruments = 31.8%
Brass Instrument = 37.2%
Step-by-step explanation:
the percent is the number of a certain instrument/ the total amount of instruments:
Total are 65 + 90 + 159 + 186 = 500
String instruments % = 65/500, divide by 5, 13/100 = 13%
Percussion Instruments % = 90/500, divide by 5, 18/100 = 18%
Wind Instruments % = 159/500, divide by 5, 31.8/100 = 31.8%
Brass Instruments % = 186/500, divide by 5, 37.2/100 = 37.2%
Check:
13 + 18 + 31.8 + 37.2 = 31 + 69 = 100, yes
