Eric's average income for the first 4 months of the year is $1,450.25, what must be his average income for the remaining 8 months so that his average income for the year is $1,780.75?

Average income for the remaining 8 months = $2,111.25

Step-by-step explanation:

Given:

Average income of 4 months = $1,420.25

Annual average income = $1,780.75

Find:

Average income of 8 months

Computation:

⇒ Annual average income = [Average income of 4 months + Average income of 8 months] / 2

⇒ $1,780.75 = [$1,420.25 + Average income of 8 months] / 2

⇒ $3,561.5 = $1,420.25 + Average income of 8 months

⇒ Average income of 8 months = $3,561.5 - $1,420.25

Average income of 8 months = $2,111.25
