Question

A group of mountain climbers begin an expedition with 270 pounds of food. They plan to eat a total of 15 pounds per day. Write and solve a linear equation to find the number of days their food will last.

Answer 1

y=15x+270 is the answer to your question per is usually the slope by the way

Answer 2

Equation : 15x = 270

Where, x = number of days,

Their food will last in 18 days.

Explanation:

Given,

Total food = 270 pounds,

Consumption of food per day = 15 pounds

Let x be the number of days,

Then, consumption of food in x days = 15x

∵ Total food will last,

If total consumption = total food

⇒ 15x = 270

Which is the required equation,

Divide both sides of the equation by 15,

We get,

x =
`(270)/(15)` = 18

Hence, their food will last in 18 days.
