Jamie is buying 5 concert tickets, and he wants his total coast to be no more than $4 above or below $80. Write an inequality that models the cost x, in dollars, of a ticket?
Answers
|80 - 5x| ≤ 4
- This is about absolute value inequality.
He is buying 5 tickets.
He wants his total cost to be in the range of 80 ± 4.
- If the cost of one ticket is $x, then we have;
5x - 80 ≤ 4
5x ≤ 84
x ≤ 16.8
- Also; 80 - 5x ≤ 4
5x ≥ 76
x ≥ 15.2
- From absolute values, since;
5x - 80 ≤ 4 and 80 - 5x ≤ 4
we can express this inequality as;
|80 - 5x| ≤ 4

Final answer:
To model the cost x, in dollars, of a concert ticket, the inequality 80 - 4 ≤ x ≤ 80 + 4 can be used.
Explanation:
To model the cost x, in dollars, of a concert ticket, we can write the following inequality:
80 - 4 ≤ x ≤ 80 + 4
This inequality states that the cost of a ticket, x, must be between $76 and $84 (inclusive),
in order for Jamie's total cost for 5 tickets to be no more than $4 above or below $80.

legnth=2/3
area=7 and 2/3
convert 7 and 2/3 to improper fraction for convenience
7 and 2/3=23/3
23/3=2/3 times width
multiply both sides by 3/2 to clear fraction
69/6=width
23/2=width
7 and 1/2=width
widht=7 and 1/2 in
(NOTE: normallly length is longer then width since legnth is the longer side, and the width is the other side)
