Question

Ajar containing only nickels and dimes contains a total of 60 coins. The value of all the coins in the jar is $4.45. If n represents the number of nickels and d

represents the number of dimes, which of the following systems of equations can be used to represent this situation.
O A n+d=4.45
0.05n+0. 10d=60
OB. n+d=60
5n+100=4.45
OC. ned=60
0.05n+0.10d=4.45
O D. 0.05n+0.10d=60
0.05n+0.10d=4.45

Answer 1

Answer: A. N+D=4.45

Step-by-step explanation: We don't know how many nickels or dimes in the jar, so to represent the unknown, we put a variable, N for the nickels, and D for dimes.

I hope this helps!!!
