Question

Eric's average income for the first 4 months of the year is $1450.25, what must be his average income for the remaining 8 months so that his average income for the year is $1780.75

​

Answer 1

$ 1,946.00

Explanation:

Average income per year=total income per month/12 months

total income=average income for first 4 months*4+ total income for 8 months

Let x represent total income total income for remaining 8 months

$1780.75=($1450.25*4+x)/12

$1780.75*12=$5,801+x

$21,369==$5,801+x

x=$21,369-$5,801

x=$15,568

The average income for the remaining eight months=x/8=$15568/8 =$1,946.00

The average income for the remaining 8 months is $ 1,946.00
