Question

Matthew has a jar of 368 nickels and imes he has been collecting. The total value of the coins is $28. 40. Which system of linear equations and solutions can be used to represent the number of nickels and dimes Matthew has inhis collection

Answer 1

D : Dimes
Explanation: I did the test

Answer 2

d = # dimes value = 10d

n = nickels = 368 - d value = 5 (368-d) summed = 2840

10d + 5 (388-d) = 2840

solve for 'd' ...the # of dimes then # nickels = 368 - d
