Aaliyah attends a private school where she must wear a uniform. Last year, the price of the uniform was $70. This year's uniform price was $63. What is the percent of decrease in the cost of the uniform?
To calculate the percent decrease in the cost of the uniform, we first need to find the difference in the prices of the uniform.
Difference = Initial Price - Final Price
Difference = $70 - $63
Difference = $7
Next, we calculate the percent decrease:
Percent Decrease = (Difference / Initial Price) * 100
Percent Decrease = ($7 / $70) * 100
Percent Decrease = 0.1 * 100
Percent Decrease = 10%
Therefore, the percent decrease in the cost of the uniform is 10%.
