Question

it is a question that i have not been able to solve and i want to learn how to do this 5d style

Answer 1

55-13=42

42/6=36 hours 

 

Answer 2

$13 of the $55 he paid was for the standing charge, so take $13 from $55=$42. All this was for hire at $6 per hour. So the number of hours is 42/6=7 hours.
