One scarf=s
One hat=h
2s+h=13
s+2h=14
h=13-2s
(plug that into the other equation)
s+2(13-2s)=14
s+26-4s=14
26-3s=14
-3s=-12
s=4
One hat=$5
One scarf=$4
5+4=9
Price of one hat AND one scarf is $9

Answer:
135
Step-by-step explanation:
First, find the volume of the cube.
s³ = Volume

Now divide 5 by 1 / 27 because you want to find how many cubes it takes to fill the prism.
5 / 1/27
5 x 27 / 1
= 135
