The combined original price for a shirt and a pair of pants is $80. After a 10% discount to the shirt and a 20% discount to the pants are applied, the combined sale price for the two items is $68. Which system of equations gives the original price $$ s$ , in dollars, of the shirt and the original price $$ p$ , in dollars, of the pants?

A.

$s + p = 80 0.10 s + 0.20 p = 68$

B.

$s + p = 80 0.80 s + 0.90 p = 68$

C.

$s + p = 80 0.20 s + 0.10 p = 68$

D.

$s + p = 80 0.90 s + 0.80 p = 68$
