: HI.
I can't figure out this question. I might of gotten it right so far but I'm not sure.
HIKING. You are hiking. the total weight of the backpack and its contents is 13 3/8 pounds. You want to carry no more than 15 pounds. Water bottles weigh 3/4 pound. How many more water bottles can you add to your backpack?
So far I tried 15 + 3/4 x n = 13 3/8
And it said in the back of my book that you subtract 13 3/8 - 13 3/8 +3/4 x n =15 - 13 3/8
So I am not sure what to do on this problem.
thank you very much. I appreciate it. This question is from textbook McDougal Littell Algebra 1

---------
1st: Figure out how much more you can carry, as follows:
15-13 3/8= 1 5/8 lbs.
2nd: Figure out how many bottles of weight 3/4 lb. will fit in that
number, as follows:
(1 5/8) / (3/4) = (13/8)/(3/4)=13/6=2 1/6
Can carry two water bottles.
Cheers,
Stan H.
