Comment from student: thank you so much for helping me figure out the question

Comment from student: Nice-- thank you

Comment from student: Hello Deina, thank you so much. I appreciate your help.

Comment from student: Ya I'm actually not into those kinds of games. But this isn't homework!! I have this math book with all these problems, but it doesnt show you how to do them. I was just wondering if you could show me how to do this same problem step by step.

Comment from student: Thank you so much! (:

Comment from student: Deina, thanks for the help with my homework! Brianna

Comment from student: please help I can not figure out how to post my questions again in the main forum.

Comment from student: . Using the above sales numbers in for your toaster company in 2007 and 2009 and by showing your work using scientific notation, find the percentage growth or percentage loss between 2007 and 2009.

Comment from student: Your toaster company’s sales were \$12,000,000 in 2007 and \$11,000,000 in 2009. Write your toaster company’s 2007 and 2009 sales in scientific notation.

Comment from student: A local computer company found the following Profit Equation for their new laptop: –x2 + 66x – 800 Using “p = 0” for the breakeven point, find the breakeven values (Hint: Try the numbers “50” and “16” when factoring).

Comment from student: A company’s revenue is the amount of money that comes in from sales before business costs are subtracted. For a single product, you can find the revenue by multiplying the quantity of the product sold, x, by the demand equation, p. The Revenue equation is “R = xp”. You are advising a local company that sells hamburgers at your state fair and have determined that the demand equation is: p = -x + 300. Substitute this equation for “p” into the previously mentioned Revenue equation

Comment from student: THANK YOU! I could not figure out where to start!!

Comment from student: Thank you Deina for taking the time to work this problem. It was a tough one for me. The only thing I changed was the decimal of -1.33333333333333 to a fraction of -4/3. Thank you again for the help, much appreciated!!

Comment from student: thank you so much for your help

Comment from student: I get it now Deina. Thanks for making it clear. You're the best.

Comment from student: Deina, thank you so much for taking your valuable time to help me. I did get the formula part (x + 7x = 120), but I couldn't go further. How and why did you go from the formula to 8x/8 = 120/8? I didn't quite get that. Is it safe to say that 105/120 the same as 87.5%? Do you think that the way the percent is written is important? Finally, what math category would this type of problem be listed and where online can I get more help with questions like this if you know? I can't tell you how much you've helped me and I appreciate it so much. Thanks again. Regards, Japcione

Comment from student: Thank you so much Deina, I greatly appreciate it. I don't know why I set it up like that. The problem wasn't as complicated as I thought it was. Thank you!
