Final answer:
Aliyah's total expense for making 4 shirts is $120, calculated by adding the cost of production and supplies per shirt and then multiplying by the number of shirts made.
Step-by-step explanation:
The question asks us to calculate the total expense Aliyah incurs when she makes 4 shirts for her small textile company. Each shirt costs her $28 to make, plus an additional $2 for supplies. To find the total expense, we multiply the cost to make each shirt by the number of shirts made and add the cost of supplies for each shirt.
So, the calculation will be ($28 per shirt + $2 for supplies) x 4 shirts = ($28 + $2) x 4 = $30 x 4 = $120. Therefore, Aliyah's total expense for making 4 shirts is $120.
