Question

Dirago Lawn Care cuts 42 lawns every week. Each lawn uses 3\16 of a tank of gas when it is cut (on average)

The cost of gas in the lawnmower is $20. How much does it cost (in lawnmower fuel only) to mow one average lawn? Show your work.

Answer 1

You are saying the lawnmower has a full tank with $20 worth of gas.

3/16 * $20 = $60/16 = $30/8 = $15/4 = $3.75 per lawn
