Question 371183: Select the set of equations that represents the following situation: The sum of two numbers is 54, and their difference is nine more than the smaller number. What are the two numbers?
a��x + y = 54; x � y = x � 9
b��x + y = 54; y � x = x + 9
c��2x = 54; 54 = x + 9
d��2y = 54; 54 = x � 9

Question 371184: Select the set of equations that represents the following situation: Mike invested $240 for one year. He invested part of it at 9% and the rest at 10%. At the end of the year he earned $23.42 in interest. How much did Mike invest at each rate of interest?
(Points : 3)
��a��x + y = 240; 0.09x + 0.10y = 23.42
��b��0.09 � 240 + 0.10 � 240 = 23.42
��c��0.09x + 0.10y = 240; x + y = 23.42
��d��x + y = 240; 9x + 10y = 23.42
