A hardware store sells two types of nails: small nails for $$0.05$ each and large nails for $$0.12$ each. On a specific day, the store sold a total of 1,500 nails and generated $$138$ in revenue from nail sales. Which of the following systems of equations could be used to determine the number of small nails, $s$ , and the number of large nails, $l$ , sold?

A.

$s + l = 1500$
$0.05 s + 0.12 l = 138$

B.

$s + l = 138$
$0.05 s + 0.12 l = 1500$

C.

$s + l = 1500$
$0.12 s + 0.05 l = 138$

D.

$s + l = 138$
$0.12 s + 0.05 l = 1500$
