Chelsea has made 6 out of 17 free throw attempts. how many consecutive free throws must she make to raise her percentage of free throws made to exactly 50%?

she needs about 8.5 throus to get to 50% which means if she has done 6 throws she needs about 2.2 more in order to reach 50%

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
