Answer:
Equation : 15x = 270
Where, x = number of days,
Their food will last in 18 days.
Step-by-step 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 = = 18
Hence, their food will last in 18 days.
