Answer:
126.4 (rounded to the nearest tenth)
Step-by-step explanation:
53,558/100 = 67739/x
67739*100=53558X
6773900=53558X
6773900/53558=x
126.4070314=X
Use Arizonia as a reference index point. Since it is set at 100, you can put the median income over 100 is equal to California median income over x. Then solve for X.
