Answer:
What was the regular price of the T-shirt?
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?
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?
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
