GQT Tuesday Mystery Cache

GQT – Tuesday

I have had a contract to keep a garden tidy. This one in particular has a substantial lawn which the owner likes being kept in perfect stripes along its length.

I charge a fixed price for the job so it is important for me to make sure I don’t go over the same ground twice whilst also producing a top quality finish.

The lawn is rectangular and is 100m long by 50m wide.

My current mower cuts a strip 0.4m wide. Taking into consideration the time taken to turn the mower and empting the grass cuttings every now and again this job takes all afternoon - four hours and ten minutes.

I am thinking of getting a bigger mower that can cut 1m wide strips. Assuming I can keep the same average speed I was wondering how much time it would save me.

Time saved = L.M hours

Whilst the grass cutting contract is an agreed fixed price it is based upon a notional labour rate of £20 per hour.

Bearing in mind I cut the grass once a week for 20 weeks and could easily get some extra work to fill in the time freed up how much extra cash could I earn during the 20 week period based on labour alone?

Extra Cash = £ NOPQ

Would this cover the cost of the second hand mower which I believe i can get for about £750

Yes R=9 No R=3
