$1,780.75?

Answer 1

Answer:

His average income for the remaining 8 months must be $2,111.25 so that his average income for the year is $1,780.75.

Step-by-step explanation:

Let the average income for the first 4 months of the year be A1

And, The average income for the remaining 8 months be A2

By condition,

Average income = A1 + A2 / 2

=> 1780.75 = 1450.25 + A2 / 2

=> 1450.25 + A2 = 1780.75 × 2

=> 1450.25 + A2 = 3561.50

=> A2 = 3561.50-1450.25 = 2111.25 (ans).
