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?
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
