QUESTION?
Step-by-step explanation:
Answer:
8.5$
Step-by-step explanation:
85 diveded by 10 is 8.5$.
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Take away 3 from both sides,
x+3<-2
-3 -3
=x<-5
answer=x<-5
hope this helps.......
