marysya [2.9K]

Answer:

Step-by-step explanation:

Household.          Year 2010.         Year 2015.           Difference

Adderley.              47,200               58,200.                11,000

Bonniville.              52,900.             62,400.                9,500

Clay City.               44,600.              57,600.                13,000

Daletown.              41,500.               54,000.               12,500

Percentage increase for Adderley = 11,000/47,200 * 100= 23.3%

Percentage increase for Bonniville = 9,500/52,900 * 100= 17.96%

Percentage increase for Clay City = 13,000/44,600 * 100= 29.15%

Percentage increase for Daletown = 12,500/41,500 * 100= 30.12%

We can now see that Bonniville is the city with the lowest rate of increase in median household income.
