Question

austen attends a private school where he must wear a uniform. last year, the price of the uniform was $40. this years uniform price is 10% less. how much are uniforms this year?

Explanation:

Step1: Calculate 10% of 40

To find 10% of 40, we use the formula \( \text{Percentage of a number} = \frac{\text{Percentage}}{100} \times \text{Number} \). So, \( 10\% \) of 40 is \( \frac{10}{100} \times 40 = 0.1 \times 40 = 4 \).

Step2: Subtract the decrease from the original price

The original price was $40, and it decreased by $4. So, this year's price is \( 40 - 4 = 36 \).

Answer:

\( 36 \)
