Andrew has $2.75 in nickels and quarters in his coat pocket. If he has a total of 15 coins, which system of equations could you use to find the number of quarters in Andrews coat pocket?

1)x+y=15

0.5x+0.25y=2.75

2)x+y=2.75

x+y=15

3)x+y=15

0.05x+ 0.25y=2.75

4) x+y=15

5x+25y=2.75

so I feel it is #3 because x+y = the number of coins(so 15 is correct)

the second part is the coins .o5=5cents and .25=25 cents.

Is this correct?

Thanks for checking my work
