Question

Aops jane averages 143 in her first 6 games her scores in her next 4 games are all the same. I f her bowling average over the 10 games is also 143 then

Answer 1

143

Explanation:

The average for the 10 bowling games is given by:

`A = (6*143+4x)/(10)`

Let 'x' be the score of each of the last four games. If her average score was 143, then the score for each of Jane's last four games is:

`143 = (6*143+4x)/(10)\\4x=1430-858\\x=143`

Jane scored 143 in each of her last four games.
