Answer:
Option C
Step-by-step explanation:
Let
x ----> the cost of the concert ticket
we know that
The total cost to be no more than $4 Above $80
so
Solve for x
The total cost to be no more than $4 below $80
so
Solve for x
therefore
The inequality that represent this problem is
<u><em>Verify</em></u>
<em>First solution (positive case</em>)
Solve for x
----> is ok
<em>Second solution (negative case)</em>
Multiply by -1 both sides
Solve for x
---> is ok
Remember that
is equivalent to
Because is a absolute value
