Question

Krysti is ordering T-shirts for 25 classmates. She knows that 60% of the classmates want the small size. In her order, Kryst mistakenly asked for 12 small shirts. How many small T-shirts

should she have ordered? What was Kryst's error in finding the number of small T-shirts?

Answer 1

Answer: Krysti's mistake was ordering only 12 small T-shirts when she should have ordered more. To figure out how many small T-shirts she should have ordered, we can start by finding out how many classmates wanted small T-shirts:

60% of 25 classmates = 0.60 x 25 = 15 classmates

So, 15 classmates wanted small T-shirts. If Krysti had ordered one small T-shirt for each of these classmates, she would have needed 15 small T-shirts. However, Krysti only ordered 12 small T-shirts, which means she is short by 3 shirts.

To avoid this mistake, Krysti should have double-checked her calculations and made sure that the number of small T-shirts she ordered matched the number of classmates who wanted small T-shirts.
