<><><><><><><><> 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? A. 126 dimes and 74 nickels B. 132 dimes and 68 nickels C. 84 dimes and 116 nickels D. 112 dimes and 88 nickels
try substituting in the values. example: A) 0.1(126)+0.05(74) and does that equal 16.3? do the same with the rest
solve for x so that x = 200 - y then plus in x in the othe requation
B) 0.1(132)+0.05(68) C) 0.1(84)+0.05(116) D) 0.1(112)+0.05(88)
does that make sense?
yes it does :)
i think its A
correct(:
thank you so much @kah.x and @RyleeC
