Question 567749
$60,700,000,000=$6.07(10,000,000,000)=${{{6.07*10^10}}}
$71,200,000,000=$7.12(10,000,000,000)=${{{7.12*10^10}}}
•	Find the increase in sales from 2001 to 2005.
${{{7.12*10^10}}}-${{{6.07*10^10}}}=${{{1.05*10^10}}}=$10,500,000,000
•	Find what percent that increase is of the 2001 sales.
If that percentage is {{{x}}} ,
{{{x/100=1.05*10^10/(6.07*10^10)}}}
So, {{{x=1.05*10^10*100/(6.07*10^10)=1.05*10^10*10^2/(6.07*10^10)=1.05*10^12/(6.07*10^10)}}}= approx. 17.298
I have seen that some of the free tutors in this website will help you for a fee, too. I have also seen advertised paid tutors on this website.
There may be tutoring agencies operating where you live. There may be local tutors advertising in supermarket bulletin boards, other local boards, local newspapers, and various websites. I suspect face-to-face tutoring works best, but some tutor may have developed a comparably efficient way to do it online.
NOTE: If you enter, in this website, a thank you note for my response, the thank you message only shows online, but it also triggers an email to me, with the message plus the email address you registered with. If a thank you note includes a further question (or ten further questions), I usually email an answer (for free). However, I am not presently set up for efficient online tutoring. This is currently my hobby, but I still have a full-time-plus day job.
