85 %
Step-by-step explanation:
We know that a basketball player made 12 out of 15 free throws she attempted.
We can calculate its percent of successful free throws as :

%
Now, If she wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85 % we can write :
(I)
In the equation (I) ''n'' represents the number of consecutive free throws she must have to raise the percent to 85 %.
We answer
a) 
b) Now we need to solve the equation (I) :
⇒
⇒
⇒
⇒ 
We found out that she needs 5 consecutive free throws to raise the percent of successful free throws to 85 %.
We can verify by replacing the value of ''n'' in the equation (I) ⇒
⇒
⇒
Answer:
' =9 93/107 days
Step-by-step explanation:
1/11+1/24
one day =35/264
35/264 -1/32
=107/ 1056- fraction of rem in a day
1 day= 107/1056
x = 1
=107/1056x=1
x=1÷107/1056
1056÷107
=9 93/107 days
