Answer :
Deepak will work for at-least 4 hours in each job
Linear Inequality in one variable:
A linear inequality in one variable that can be written either in the form of,
a+bx<0
a+bx≤0
a+bx>0
a+bx≥0
where,
where a and b are real numbers and a≠0 a ≠ 0
For the given question,
Deepak charges $30 for each job he does plus an additional $15 for each hour he works.
He only accepts jobs if he will earn at least $90 per job.
If,
x is number of hours Deepak works in each job then,
required inequality can be written as,
30 + 15x [tex]\geq[/tex] 90
15x ≥ 90 - 30
15x ≥ 60
x ≥ 60/15
x ≥ 4
thus,
we conclude that Deepak will work for at-least 4 hours in each job.
