Answer:
let x be chips and y be sodas
8x + 4y = 5 ---> for the first hint
4x + 8y = 7------> second hint
0.25 cents is how much chips costs
and 0.75 cents is how much sodas costs
-- The trains start moving at the same time.
-- The space between them is initially 252.5 miles.
-- They reduce the distance between them at the rate of (124.7+253.5)=378.2mph.
-- It will take them (252.5 / 378.2) = 0.6676 hour to meet.
That's 40min 3.49sec .
-- After tooting and puffing toward each other for 8 minutes, they still have <em>32min 3.49sec</em> to go before they meet each other. We're all hoping that they're on different tracks.
x/10 + x/4 = 21 /*40
4x + 10x = 840
14x = 840
x = 60 = total number of points the team scored
|3+10|=|3|+|10|
|13|=|13|
13=13
