Question

Chloe has a bird feeder in her yard. When it is full of bird seed, it weighs 1234 pounds. The birds eat 112 pounds of bird seed each week. She refills the bird feeder when it weighs less than 3 pounds. Which solution represents how many weeks, w, it will take until Chloe refills the bird feeder?

Answer 1

Chloe will refill the bird feeder every 11 weeks.

Explanation:

Since Chloe has a bird feeder in her yard, which when it is full of bird seed, it weighs 1234 pounds, and the birds eat 112 pounds of bird seed each week, since she refills the bird feeder when it weighs less than 3 pounds, to determine which equation represents how many weeks, W, it will take until Chloe refills the bird feeder, the following calculation must be performed:

(1234 - 3) / 112 = W

1231/112 = W

10.99 = W

So, Chloe will refill the bird feeder every 11 weeks.
