Uncle percy sold t-shirts at the show. now he only has 10% of the t-shirts he started with. if he has 25 t-shirts now how many did he start with

250 T-shirts

Step-by-step explanation:

The data we have is

T-shirts        percentage

 25          ⇒      10%

and we want to know how many t-shirts were the 100% that he had initially, which i will call x:

T-shirts        percentage

 25          ⇒      10%

  x          ⇒      100%

now we solve this as a rule of three: multiply cross quantities and dividide by the remaining quantity:

He started with 250 T-shirts

answer: it is 1: 47 pm
