Grandma is removing weeds from her garden. She estimates that there are 250 weeds in the garden at the moment, and she can remove weeds at a rate of 5 per minute. At this rate how many minutes (m) will it take Grandma to only have 30 weeds remaining in the garden?
Equation: __
solution:__
Equation: 250 - 5m = 30
Solution:
250 - 5m = 30
Subtract 250 from both sides:
-5m = -220
Divide by -5:
m = 44
It will take Grandma 44 minutes to only have 30 weeds remaining in the garden.
