Answer:
Explanation:
To calculate the percentage increase in the estimated number of millionaire households from 2017 to 2018, we need to follow these steps:
Determine the estimated number of millionaire households in 2017 and 2018. Let's call these numbers A and B, respectively.
Subtract the 2017 number from the 2018 number: B - A = C
Divide the result from step 2 by the 2017 number: C / A = D
Multiply the result from step 3 by 100 to convert it to a percentage: D * 100 = E
Round the result from step 4 to the nearest tenth of a percent.
In this case, we are given the percentage increase, so we can skip steps 1-4 and simply round the given percentage increase to the nearest tenth of a percent.
