Answer: 4 points per boy and 7 points per girl
Step-by-step explanation: first we have to find out how many points total the girls scored and how many the boys scored. Since the girls scored 13 more points, we can do 29-13=16. then divide that by two because there are the girls and the boys. 16/2=8. the boys scored 8 points total. but we have to add the 13 and 8 for the girls. 13+8=21 then divide each by the number of girls and boys. so, the boys it would be 8 total points the boys scored/2 boys who scored=4. each boy scored 4 points. now the girls. 21 points scored by the girls/the 3 girls who scored=7 points per girl. so, each boy scored 4 points and each girl scored 7 points.
