Answer:
12 shirts.
Explanation:
We have been given that Lenox ironed 1/4 of shirts over the weekend and splits the remainder over the next 5 evenings, and has 40 shirts.
First of all, we will find the shirts ironed on weekend by calculating 1/4 of 40 as:
Since Lenox ironed 10 shirts over weekend, so 30 shirts are remaining.
Since Lenox splits the remainder over the next 5 evenings, so we will divide 30 by 5 to find shirts ironed each day as:
To find shirts ironed on Thursday and Friday we will multiply 6 by 2 as:
Therefore, Lenox will iron 12 shirts on Thursday and Friday.
