He takes minimum 10 hours to make a very large yard .

Step-by-step explanation:

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

$20+5x\geq 70$

Subtracting 20 from both side then we get the inequality

$5x\geq 50$

By simplication we get

$x\geq \frac{50}{5}$

By dividing we get

$x\geq 10$

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