Question 755007: I need help solving word problems. I always have trouble with them. Here's my problem, and then I'll follow it with what I tried.
Trevor has just finished writing a book. The publisher has given him two options: receiving $20,000 up front and 8% of the sales of the book or $50,000 up front and 5% of the sales of the book. What do the sales have to be for Trevor to make the same amount from each option?
Here's what I tried doing:
I want this:
option #1 = option #2
$20,000 + 8%x= $50,000 + 5%x

Simplifying:
20,000 + 0.08x = 50,000 + 0.05x
Solving:
20,000+ 0.08x- 0.05x=50,000
0.03x + 20,000= 50,000
0.03x +20,000 - 20,000 = 50,000-20,000
0.03x= 30,000
Then, dividing both sides by 0.03 leaves me with:
x= 1,000,000
Is this correct?
Thank-you for your time!
