the median household in the United States increased by a rate of 0.25% each month between 1980 and 1985 if the median household income was $42,000 in 1980 what was the median household income after 5 years?​

Median U.S. household income increased 6.8% to $68,700, the U.S. Census Bureau said Tuesday. That followed advances of 3.1% in 2016, 1.8% in 2017 and 0.9% in 2018. On an inflation-adjusted basis, median income last year was the highest on records dating to 1967.

Step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
