\[\text{Solve}[\{0.8 c+0.4 t=12.8,c+t=24\}] \]Work it out. c should equal 8 .

but how do I work it out
anonymous
  • anonymous
c + t =24, thus, t = 24 - c Plug 24-c for each occurrance of t in the first equation and solve the result for c.
anonymous
  • anonymous
so then it would be 3?
anonymous
  • anonymous
Sorry, occurrance should have been spelled, occurrence.
anonymous
  • anonymous
so u said that c would equal 8 then wouldn't t equal 3
anonymous
  • anonymous
0.4 (24 - c) + 0.8 c = 12.8 0.8 c - 0.4 c + 9.6 =12.8
anonymous
  • anonymous
so what do I do next
anonymous
  • anonymous
0.4 c = 12.8 - 9.6 0.4 c = 3.2 c = 8
anonymous
  • anonymous
so how did u get 9.6
anonymous
  • anonymous
so is 8 the answer or the value of c
anonymous
  • anonymous
0.4 (24 - c) + 0.8 c = 12.8 9.6 + 0.8 c = 12.8
anonymous
  • anonymous
"so is 8 the answer or the value of c ? " Yes.
anonymous
  • anonymous
so the answer would be 16 right
