A STORE OWNER PLANNED to raise the price of a T-shirt by 10% - he accidently labeled 10% though. The new price is what percent less than the raised price? Mixed number and omit the % sign.

you can plug in a number: 100

so 100-10=90
and 100+10=110
110-90=20
this becomes 20/110*100%=200/11=18 and 2/11(mixed number)

Need to know the cost for t-shirt and the percentage owner accidentally displayed

To find the answer, we can break down the problem into a few steps:

Step 1: Let's assume the original price of the T-shirt was $100.
Step 2: The store owner planned to raise the price by 10%, which means an increase of $10 ($100 * 10% = $10).
Step 3: However, the store owner accidentally labeled the new price as $10 instead of $110.
Step 4: Now, to calculate the percentage decrease from the incorrect labeled price, we find the difference between the raised price and the incorrect labeled price: $110 - $10 = $100.
Step 5: Finally, to determine the percentage decrease, we divide the difference by the raised price ($100 / $110) and multiply it by 100 to convert it into a percentage: (100/110) * 100 = 90.91.

Therefore, the new price is approximately 90.91% less than the raised price.
