If the average (arithmetic mean) of the assessed values of x houses is $212000 and the average of the assessed values of y other houses is $194000, what is the verage of the assessed values of the x+y houses?
1) x+y = 36
2) x =2y
Are u sure answer is C. Am getting b
sum of x houses is 212000 * x
sum of y houses is 194000 * y
so average is sum/total ==> 212000x + 194000y/(x + y)
statment 1 x + y =36 is not sufficient to solve above
statment 2 x = 2y. Is good enough to solve the above
B for me as well
How come C?
