cut 15 lawns at 10 dollars a lawn. that would only make 150$ so 30 lawns at 10$ each or 15 lawns at 20$ each orGarden for $10 then if you do 12 gardens a day you'll get $120 then the next day do 12...
you take 1 of the 1s and put it in the tenths place. Then you add the 1+1+1+1+1 and put the answer(5) in the ones place! that is how you get 15 out of 1 1 1 1 1 1.
