Question

council? One day 3% of the sweatshirts made at a factory were defective. 15 sweatshirts were defective. How many sweatshirts were produced at the factory that day?

Answer 1

Let x sweatshirts were produced at the factory.

The number of defective shirts is 15.

Equate 3% of x to 15, to obtain the value of x.

$\begin{gathered} \frac{3}{100}\times x=15 \\ x=\frac{15\cdot100}{3} \\ =500 \end{gathered}$

So 500 sweatshirts were produced at the factory.
