Been working at this for a solid hour....one math question...Please help! A container holds a combination of dimes and nickels. There are 200 coins in all,
and their total value is $16.30. The system of equations models this situation, where x is the number of dimes and y is the number of nickels.
x + y = 200
0.1x + 0.05y = 16.3
How many dimes and nickels are in the container?
126 dimes and 74 nickels
132 dimes and 68 nickels
84 dimes and 116 nickels
112 dimes and 88 nickels
