Can you tell me what the Word problem was?

anonymous · Answer

ok

anonymous · Answer

40 candy bars and 100 drinks cost $125 and 80 candy bars and 84 drinks cost $163..how much is each candy bar?

anonymous · Answer

Solve for x or y in one of the equations

anonymous · Answer

x= 25 - 5/2 y  ?

anonymous · Answer

x= 5/8 y?

anonymous · Answer

40x+100y=125
100y=-40x+125
y=-2/5x+5/4

anonymous · Answer

ok

anonymous · Answer

Now you know what y is so plug that into the other equation and solve for x

80x+84(-2/5x+5/4)=163

anonymous · Answer

Thx.

anonymous · Answer

right..Understand the theory-just seems overly complicated...usually the numbers are all nice and round and even... 84 times negative 2/5x + 5/4 makes my head spin..

anonymous · Answer

Well fractions just multiply straight across top and bottom....think of 84 as 84/1
