Joanna has a total of 50 coins in her purse. • The coins are either nickels or quarters.
• The total value of the coins is $4.35.
Which system of equations can be used to determine the number of nickels, n, and quarters,
q, that Joanna has in her purse?
0.05n + 0.25q = 4.35
50n + 50q= 4.35
On +9= 4.35
50n + 50q = 4.35
On+q=50
0.05n +0.259 = 4.35
0.05n +0.25 = 50
n +9= 4.35
