Assume every item you sold was a case.
You would've gotten : 48 x 10 = $480.
But in reality, you only got $350, so it's a $130 difference.
Replace 1 cell phone case with 1 t-shirt -> the difference go down 5 every time. (for example, if you sold 47 case and 1 t-shirt, the difference go from $130 to $125)
So, the amount of t-shirt you sold was 130 : 5 = 26 (t-shirts)
And, you sold : (350 - 26 x 5) : 10 = 22 (cases)
Recheck : 26 + 22 = 48 items, and 26 x 5 + 22 x 10 = 130 + 220 = 350.
