The inequality that models the given situation is:
y*$22 + x*$38 ≤ $220
And some solutions are (1, 1), (1, 2), (2, 2).
<h3>
Which inequality models the given situation?</h3>
To find the inequality, we first need to define the variables that we will use, the variables are:
- x = number of pants bought.
- y = number of shirts bought.
Knowing the price of each individual item, the total cost will be given by:
C = y*$22 + x*$38
And Lee has $220 to spend, so the maximum amount that he can spend is $220, then we have the inequality:
y*$22 + x*$38 ≤ $220
Now, to find solutions you just need to find some values of x and y that make the inequality true, for example, one solution is x = 1 and y = 1.
1*$22 + 1*$38 ≤ $220
$60 ≤ $220
This is true, so (1, 1) is a solution.
Another solutions are (2, 2), (1, 2), (0, 3), etc.
