Final answer:
The total cost of an order of 44 shirts can be found by calculating the cost of the first 30 shirts and the cost of the additional 14 shirts.
Step-by-step explanation:
To determine the total cost of an order of 44 shirts, we need to consider two different price ranges: the first 30 shirts cost $19 each, and the additional 14 shirts cost $15 each.
So, the cost of the first 30 shirts is 30 x $19 = $570.
The cost of the additional 14 shirts is 14 x $15 = $210.
The total cost of the order is $570 + $210 = $780.
Therefore, option d) $731 is incorrect. The correct answer is option e) $780.
