Adina has a total of $1.65 in nickels and dimes. The number of dimes is 6 more than the number of nickels. How many coins are there of each type? Choose the correct system of equations needed to solve this problem.

A
0.10d+0.05n=60.10d+0.05n=60.10d+0.0 5n=6

n+d=1.65n+d=1.65n+d=1.65

B
d=n+6d=n+6d=n+6

0.05n+0.10d=1.650.05n+0.10d=1.650.0 5n+0.10d=1.65

C
n=d+6n=d+6n=d+6

0.10d+0.05n=1.650.10d+0.05n=1.650.1 0d+0.05n=1.65

D
n=d+6n=d+6n=d+6

0.05n+0.10d=1.650.05n+0.10d=1.650.0 5n+0.10d=1.65
