Math Problem Solving Question?

Question:

You are hiking. The total weight of your backpack and its contents is 13 3/8 pounds. You want to carry no more than 15 pounds. How many extra water bottles can you add to your backpack if each bottle weighs 3/4 pounds?

The equation I used:

15/1 – 13 3/8 = 13/8

13/8 x 4/3 = 2.1666 water bottles

Would 2.166 water bottles be the answer? That doesn’t sound right; would I round it down to 2 water bottles?

Here’s what I figure: 120/8 – 107/8= 13/8, which you have right. You’ve also got the number right for the equation you’ve used to get 2.1666666 water bottles. You would have to round down to 2, because, you can’t have a decimal amount of water bottles. Good job!

2 water bottles is the correct answer. You can’t have .166 of a water bottle! You could partially fill one, of course. . . . . but I’m sure that isn’t the answer. The answer is 2.

yes round it down… but in case your teacher is weird…put down the equation and the answer you came out with then write ” which equals 2 water bottles” and circle it so he can seeyou did the work right adn if he has any questions you can explain how you didnt know which answer he was looking for

Yes. I’d say 2. two bottles is an extra 1.5 lbs. If you add an extra .75 lbs to your current sum, you’d go over 15 lbs.

2x + 2y = 20 using the simultaneous method 2x – 2y = 4 ____________ 4x = 24 ( divide by four) x = 6 substitute x in one of the two equations 2x + 2y = 20 2 (6) + 2y = 20 12 +2y = 20 2y = 20 – 12 2y = 8 (divide by 2) y = 4 Answer : X = 6 , Y = 4

if your hiking for like 10 miles your back is goin to hurt your back and then you will have to go to a chiropractor and that would suck so i would take some stuff out of your backpack know what i mean?if your only going for a mile hike go ahead and take the water bottles.im good at giving advice

ya, just take it down to 2 because you cant carry a fraction of a waterbottle. i guess you could empty it partly but i think the best answer is 2
