Given

Jack charges a falt fee  per yard = $20

Jack charges  an additional money per hour = $5

He wants to make sure that he makes at least $70 doing yard work for client by making   a very large yard

Let , he takes x  hour for making a very large yard

Therefore , we make an inequality

Subtracting 20 from  both side then we get the inequality

By simplication we get

By dividing we get

Hence, he takes atleast  10 hours for making a very large yard if he doing yard work and makes atleast $70 .
