Answer:

this is ez

Step-by-step explanation:

2.5 g converted to kg: 2.5 g x 1 kg/1000 g = 0.0025 kg = 2.5x10-3 kg

cm3 converted to m3: 1 cm3 x 10-6 m3/cm3 = 1x10-6 m3

Thus, the conversion of 2.5 g/cm3 to kg/m3 would be 2.5x10-3 kg/10-6 m3 = 2.5x103 kg/m3 = 2500 kg/m3

Let price of one scarf be $x 
Price of the other is 3 more than $x
 Therefore price of the other scarf =$x +3
 The total price she paid = $25.00
 That is, x+x+3=25
  2x+3=25
  2x=25-3
  2x=22
  x=22/2
  x=11
 The price of one scarf is $11 and the price of the other is 11+3=$14
 The price of the expensive scarf =$14.
