what question is being asked in this word problem?

Step-by-step explanation:

It is given that:

Jill had $90.

         i.e. the amount she spent on buying skirt=42/2= $ 21.

         Let x be the regular price of T-shirt.

        i.e. the amount she spent on T-shirt=x-8.

Before sales tax, the total cost of the clothes was $31.

Hence, total cost=cost of skirt+ cost of t-shirt

i.e. 31=21+x-8

i.e.  21+x-8=31

i.e. 21-8+x=31

⇒  13+x=31

⇒ x=31-13

⇒  x=18.

Hence, the regular price of t-shirt is $18.

We are asked to find the regular price of the t-shirt?
