4 times 6 equal 24 and 5 times 7 is 35 and 2 times 1 is 2 so 35+24+2 and it equals 61
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.
H=-9/2
Divide both sides of the equation by -36
Any expression divided by itself equals 1
