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?

Answer 1

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%.
