What question is being asked in this word problem?

what is the regular cost of the t-shirt purchased by Jill.

What is the regular price of the skirt?

$42

How much money does Jill have left?

without considering sales tax, Jill has $90 - $31 = $59 left. If I use the sales tax from where I live, the sales tax = $1.86, so the money that Jill will have left = $59 - $1.86 = $57.14

How much does the T-shirt normally cost?

$18 (same as question 1)

What is the amount Jill pays in sales tax?

since you do not include the sales tax % in the question, I will simply use the sales tax from where I live = $31 x 6% = $1.86

Step-by-step explanation:

skirt $21

t-shirt = p - $8

before sales tax, total cost was $31

$21 + p - $8 = $31

p = $18
