1. A collection of nickels and dimes has a value of $1.85. The value of the dimes is $0.10 less than twice the value of the nickels. Which
system of equations can be used to find the number of nickels and
the number of dimes?

A. n+d = 185; n-d = 1
B. n+d = 185; 2n-d = 1
C. 5n+10d = 185; d = 2n - 1
D. 5n + 10d = 185; n - d = 1
