Answer:
The inequality that describes the problem is given as follows:
x ≤ 75.
How to obtain the inequality?
To describe the inequality in this problem, we need to obtain the upper bound of the total amount that Ted and his friends are expected to spend.
To obtain the upper bound of the total amount, the relevant information is given as follows:
Ted and his friends decided to split the bill evenly among the 5 of them.
Ted figured that each person will pay no more than $15.
Hence the upper bound of the total amount is calculated as follows:
5 x $15 = $75.
The upper bound of $75 means that in total, they are expected to pay at most $75, hence the inequality that describes this problem is given as follows:
x ≤ 75.
