The question mentions Madelyn has $400 to purchase new clothes.
The total new clothes price = selling price of the school cloth + sales tax.
Is amount left post purchase is LESS THAN $50 ? STATEMENT 1:
(1) The total price of Madelyn's clothes was less than $400.
The total price was less than $400. Less can be any amount $1, $2 or $399 or any value less than $400.
Not sufficient. Options A and D are out.
STATEMENT 2:

No sales tax. Thus total price = selling price of new clothes.
we don’t have any value pertaining to total price or selling price.
Not Sufficient. We have ruled out option B also. COMBINING STATEMENT 1 and STATEMENT 2: We have options C and E now.
