Easier Algebra Question
I know this question isn't that hard, but the book I'm working with has a different answer than what makes sense to me, I think it might be incorrect, but I would like verification that I am right. Please show the work and rationale, just in case I am off. Thanks!
A car dealer sells a SUV for $39,000, which represents a 25% profit over the cost. What was the cost of the SUV to the dealer?

Re: Easier Algebra Question
100% + 25% -->
25% times 5 -->
25% + 25% + 25% + 25% + 25% -->
where 4 of them are the original price.
So 4/5 times $39000 is your answer.
Or 39000 divided by 1.25 is your answer.
$31200 is dealer cost.
Note that 31200 divided by 4 is $7800 and that is the profit made.
