p + s = 5, p = 5 - s
12p + 25s = 160
Substitute:
12(5 - s) + 25s = 160
60 - 12s + 25s = 160
13s = 100
s = 7.69, which makes no sense because you can't have part of a shirt.
If he buys 5 shirts and no pants, he will have spent 125, which is less than the budget. If he buys 5 pants and no shirts, he will have spent 60, which is likewise less than the budget.
Here's a way the problem will work:
let p + s = 9, NOT 5
12p + 25s = 160
let s = 4, lest p = 5
12(5) + 25(4) = 160
160 = 160
Did you type in the question correctly??

Although I think that perhaps I'm suppose to get different number like 3 for shirts and 2 for shorts for the 5 items in suppose to get03/08/19

Maybe a different combination of number?03/08/19

And plus I have to graph the inequalities, so if you dont mind can you help me on this03/08/19

There are several answers that yield a number less than $160: 5 of each, 1 and 4 of each, 2 and 3 of each. None uses a total of $160. You mention the word inequalities. So, shirts are 5 or less down to zero and pants are five or less down to zero on a graph.03/09/19

Thats what the question in my hw says yet it didnt work because I got a decimal similar to what you got03/08/19
