Correct!
Wrong!

Explanation:

First, we have to determine the take-home pay for each of the two years, 2020 and 2021

In 2020, Mary paid the following in taxes: $48,200 x .14 = $6,748

$48,200 - $6,748 = $41,452 take-home pay for 2020

In 2021, Mary paid the following in taxes: $51,800 x .16 = $8,288

$51,800 - $8,288 = $43,512

To find the average for the two years, add $41,452 and $43,512 and then divide by 2:

$41,452 + $43,512 = $84,964

$84,964 ÷ 2 = $42,482
