|  Thanks for the input, guys. I was close....I guess. ha This is what I came up with. (Actually, one of several equations I came up with....don't know which is correct, though. ha I hate math!!!) 24 + .60x = 32 24 - 24 + .60x = 32 - 24 .60x = 8 .60x / .60 = 8 / .60 x = 7.5 300 + 7.5 = 307.50 miles |

I wish I could remember how to do the powers. There should be a chapter explaining that in your book it should have examples & be very clear.

| Thanks! I hope it is correct. I'll find out tonight. I've been stressing over this paper all week. This is only pre-algebra! What am I going to do when I get to the real classes?!!  I am beginning to question my decision to go back to school! What was I thinking?! |

| Good luck! Please post back the correct answer so we can all stop thinking about it! Oliver's Mom's got a good idea, ask a high schooler, it's normal math to them! KC Cutie, 7.50 miles at .60 mile would cost you 4.50 (4.20 for 7 miles, plus .30 for the 1/2 mile) and you have $8.00 to spend, so sorry your computation isn't correct. Always work the problem backwards - we ususally know the answer, but just don't know how we got it. Last edited by Lacy's Mom; 09-12-2006 at 07:15 AM. |

I think your algebra looks fine here, the equation itself looks fine. I'm thinking though that going from your 4th to 5th line that you made a mistake in your math(I could be doing something wrong myself though). I think 8/.6 is 13.333 not 7.5. Before seeing your answer I did it like this 300+ (32-24)/.60 = X which is basically the same thing as yours just written in a diff order, but when you work it out it because of the orders of operation is it worked in the same order.

| Look at Hickey's reply - I just looked at your answer and knew it wasn't right, but 8 divided by .60 is 13.33333 not 7.50 so maybe it was just a math error. I'll take a look at your equation again. I looked, your equation was just fine, just a small error in simple division! You've got it! |
