Answer: 20%.
Step-by-step explanation:
Given, The price of a shirt is marked down from $12.50 to $10.00.
Previous price = $12.50
New price = $10.00
Change in price = Previous price - New price
= $12.50 - $10.00
= $2.50
Now, the percent decrease of the shirt = ![\dfrac{\text{Change in price}}{\text{Prevoius price}}\times100](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BChange%20in%20price%7D%7D%7B%5Ctext%7BPrevoius%20price%7D%7D%5Ctimes100)
![=\dfrac{2.50}{12.50}\times100\\\\=20\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B2.50%7D%7B12.50%7D%5Ctimes100%5C%5C%5C%5C%3D20%5C%25)
Hence, the percent decrease of the shirt = 20%.

![\sqrt{\pi } = 1.772](https://tex.z-dn.net/?f=%20%5Csqrt%7B%5Cpi%20%7D%20%3D%201.772)
![\pi = 3.142](https://tex.z-dn.net/?f=%5Cpi%20%3D%203.142)
![2 \times \pi = 6.283](https://tex.z-dn.net/?f=2%20%5Ctimes%20%5Cpi%20%3D%206.283)
![{\pi}^{2} = 9.869](https://tex.z-dn.net/?f=%20%7B%5Cpi%7D%5E%7B2%7D%20%3D%209.869)

2times pi =6.283
square root of 50= 7.071
pi squared/2= 3.289
