A vendor sell h hot dogs and s sodas. If a hot dog costs twice as much as a soda, and if the vendor takes in a total of d dollars, how many cents does a soda cost?
A)100d/(s+2h)
B)(s+2h)/100d
C)d(s+2h)/100
D)100d(s+2h)
E)d/100(s+2h)

• A)100d/(s+2h)
  
  If S is the cost of soda in cents, then
  h*2S +s*S = 100*d
  S = 100d/(s+2h)

• c1=cost of hot dogs
  c2=cost of sodas
  c2=2c1
  total cost=d
  d=hc1+sc2
  =h(2c2)+s(c2)
  =c2(s+2h)==>c2=d/(s+2h)
  in cents,c2=100d/(s+2h)
