Step-by-step explanation:
2.9(105)(7.2)(102)
5(10−8)
=
(2.9)(100000)(7.2)(102)
5(10−8)
=
(290000)(7.2)(102)
5(10−8)
=
2088000(102)
5(10−8)
=
(2088000)(100)
5(10−8)
=
208800000
5(10−8)
=
208800000

Step-by-step explanation:
(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
