A collection of 15 coins consists of nickels and dimes. The total value of the coins is $1.10. If $n$ represents the number of nickels and $d$ represents the number of dimes, which of the following systems of equations can be solved to find $n$ and $d$ ?

A.

$0.05 n + 0.10 d = 15$
$n + d = 1.10$

B.

$0.05 n + 0.10 d = 1.10$
$n + d = 15$

C.

$0.10 n + 0.05 d = 1.10$
$n + d = 15$

D.

$0.05 n + 0.10 d = 1.10$
$15 (n + d) = 1.10$
