Robert started to save money to purchase a new game console. His savings at the end of the first week included a jar of 368 nickels and dimes. The total value of the coins was $24.40. Which system of equations below would be the best to use to find the number of nickels and dimes Anthony had at the end of the first week? a. n+ d = 368
5n + 10d = 24.40

b. n+ d = 24.40
0.05n + 0.10d = 368

c. n + d = 368
0.05n + 0.10d = 24.40

d. n + 9 = 368
0.5n + 0.10d = 24.40
