Answer:
mp=sp+25%ofsp=1.25sp
mp=1.25sp
sp=1/1.25×mp=0.8mp
cp=mp-30%ofmp=0.7mp
discount=mp-sp=mp-0.8mp=0.2mp
- discount %=discount/mp×100%=0.2mp/mp×100%=20%
- profit=sp-cp=0.8mp-0.7mp=0.1mp
- profit%=profit/cp×100%=0.1mp/0.7mp×100%=0.1×100/0.7%=10/0.7%=14.28%
6 3
---- * ----
13 c
this is a proportion...so we cross multiply
(6)(c) = (3)(13)
6c = 39...divide both sides by 6
c = 39/6 which reduces to 13/2 or 6 1/2 <== ur answer
Answer:
Step-by-step explanation:
.6(2k-3)=3(4k+5) foil
1.2K-1.8=12k+15 subtract 1.5k from both sides
-1.8=10.8k+15 subtract 15 from both sides
-16.8=10.8k divide by 10.8
k= -1.5
