Dear ZaireMcfalane33, if you subtract with fraction strips the answer will be smaller, but if you add with fraction strips the answer will be bigger.
Answer:
Step-by-step explanation:
the perimeter P=2(L+W)=54
P=2L+2W=54 OR L+W=27
we know that L=3W+3
P=3W+W=27-3
4W=24
W=6 CM
L=21CM
(1/5)x + 8
This will find 20% of the wholesale cost and add the $8 markup, where 'x' is the wholesale cost
