Question

PLEASE HELP! A collection of nickels and quarters has a total value of three dollars and contains 32 coins. Which of the following systems of equations could be used to find the number of each coin?
N + Q = 32 and 5N + 25Q = 3
N + Q = 32 and .5N + .25Q = 3.00
N + Q = 32 and .05N + .25Q = 300
N + Q = 32 and .05N + .25Q = 3.00

Answer 1

Answer:

The second equation B is correct

Step-by-step explanation:

N + Q = 32 and .5N + .25Q = 3.00

unlike the other equations this equation has the correct input for how much a quarter and nickel are worth relevant to the dollar amount rather than the coin amount.
