You want to buy something that costs $98, and it's on sale for 30% off. What is the item's sale price?
First, convert the 30% to a real mathematical number. For percents, this is always done by dividing the 30% by 100%, or 30% / 100% = 0.300.
Second, find out what 30% of $98 is. This is the amount of the sale discount. This is always found by mulitplying 0.300 by the item's cost $98, like this:
0.300 x $98 = $29.40.
So for this sale, you'll save $29.40 on this item.
This means, the cost of the item to you is
$98 - $29.40 = $68.60.

Bob: 112.96 divided by 138=0.81855072463

Carl: 142.78 divided by 209=0.68315789473
so about 68 cents per mile
so ya i am a little confused but heres what i got
6.40x+9.90(154-x)=1230.90

X=84 for child
154-84=70 for adults
