Answer:
I used a little bit of the question i am on Right Now but the answer is in there somewhere
Step-by-step explanation:
ratio for boys: 3 soccer/5 basketball
ratio for girls: 7 soccer/1 basketball (I think you have a typo when you say "...number of boys who enjoyed basketball
of 7:1" because boys and girls were surveyed separately.)
that said...
90 boys enjoy soccer
3*30/5*30=90 boys enjoy soccer/150 boys enjoy basketball
90+150=240 boys and therefore 240 girls
7/1 is the ratio for girls
7+1=8, 240/8=30
7*30/1*30=210 girls enjoy soccer/30 girls enjoy basketball (210+30=240)
