Basically you have to convert the equalities in each box.
I'll help you figure out what the equalities are and hopefully you can figure it out from there.
Milli= .001
Centi= .01
Deci= .1
Unit base=1
Deka= 10
Hecto= 100
Kilo= 1000
In the first box, it asks for you to convert a millimeter into a meter
1mm=.001m
If you have any more trouble, please message me. I'd be happy to help

Please mark brainliest.
(3c+s)(100-20)/100=100 multiply both sides by 100
(3c+s)80=10000 divide both sides by 80
3c+s=125 subtract 3c from both sides...
s=125-3c....now let's look at the second situation...
(4c+2s)(100-40)/100=120 multiply both sides by 100
60(4c+2s)=12000 divide both sides by 60
4c+2s=200 divide both sides 2
2c+s=100 subtract 2c from both sides
s=100-2c, and from earlier we saw that s=125-3c, since s=s:
100-2c=125-3c add 3c to both sides
100+c=125 subtract 100 from both sides
c=25, and since s=100-2c
s=50
So cds cost $25.00 and sweatshirts cost $50.00
