Question

A group of mountain climbers begin an expedition with 250 pounds of food. They plan to eat a total

of 12 pounds of food per day. Write and solve a linear equation to find the number of days their
food will last.

Answer 1

250=12x

250/12=20.8

12/12=1

20.8 x 1 = 20.8

Answer 2

y=-12x+250

If you graph it you will get that it only lasts for 20.833 days

Explanation:

The minus twelve is the twelve pounds they eat per day, the positive 250 is the amount of food they start with. If you graph the above equation in desmos you should get the right graph if you need it. But it should last 20.833 (or just round to 21) days.
