Unit price of jeans = $22 => price of two pairs of jeans = 2*$22 = $44
unit price of t-shirts = $8
Money available = $120
Sara plans to buy two pairs of jeans, and as many t-shirts as possible (x) within the available budget of $120.
The constraint inequality is therefore
2*22+8x ≤ 120.................................(1)
If (1) is simplified, it becomes
44+8x ≤ 120
8x ≤ 120-44
x ≤ 76/8
x ≤ 9.5 => she can buy a maximum of 9 t-shirts.
