Homework Help: math

Posted by B8 on Saturday, January 11, 2014 at 7:57pm.

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?


0.05x+ 0.25y=2.75

4) x+y=15
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
