Question

the cost of lawn maintenance varies directly with the size of the lawn. If the monthly maintenance on a 4000-square foot lawn is $280 then what is the maintenance for a 6000 square foot lawn

Answer 1

Answer: The cost of maintenance for a 6000 square foot lawn is $420.

Step-by-step explanation:

Since we have given that

Cost of monthly maintenance on a 4000 square foot lawn = $280

We need to find the cost of monthly maintenance on a 6000 square foot lawn.

Since the cost of lawn maintenance varies directly with the size of the lawn.

So, it becomes,

`(4000)/(280)=(6000)/(x)\\\\(100)/(7)=(6000)/(x)\\\\x=(6000* 7)/(100)\\\\x=\$420`

Hence, the cost of maintenance for a 6000 square foot lawn is $420.
