To determine which option is cheaper, we need to set up an inequality where the cost from Company A is less than the cost from Company B.
Let's define the total cost for Company A as C_A and the total cost for Company B as C_B.
C_A = 50 + 25n
C_B = 10 + 30n
We want C_A < C_B, so:
50 + 25n < 10 + 30n
Subtract 25n from both sides:
50 < 10 + 5n
Subtract 10 from both sides:
40 < 5n
Divide by 5:
8 < n
So, the inequality that represents the number of shirts Kiere can order so that Company A is the cheaper option is n > 8.
Therefore, the answer is:
A. n > 8
