| A rental car with 300 miles for $24. 60 cents for each additional mile. If I have $32, how far can I go? I just need to know how to write the equation for the above. Also, on exponents, if you have 10^8 - 5^4, do you subtract the powers? Thanks for any help!!! |

| I can't think of a single equation for the first one. It seems like you would need two parts such as: (32 - 24) = .60x * (32-24) divided by .60 = x (changed .60 sides so did the opposite) 8 divided by .60 = x 13.333333 = x * you would need parenthesis here to follow the rules of order (P,E,M,D,A,S) Please (paren) Excuse (eponents) My (multi) Dear (div) Aunt (add) Sally (sub) Then, x plus 300 = y 13.33333 plus 300 = y 313.33333 = y The exponent problem I don't see any way to simplify the equation since the bases are different. 10^8 - 5^4 = X 100,000,000 - 625 = 99,999,375 |

| Did you also notice the title "Pre-Algebra"! Geez, my kids were taking Calculus before they graduated from high school. They were even receiving college credits for a lot of the courses they took. |

$32-$24 = 8 So you have $8 to which you multiply the 60 cents to and get = 8.00 x .60 = 4.8 move the decimal over or just multiply 8 x 60=480 Now 480 miles minus the 300 = 180

| Just for curiosity sake, I'm giving this one to my son (9th grader) as soon as he gets home from school today. lol. ...He should know this stuff, especially since he's been getting these types of problems the past few years, but we'll see. lol. You know kids, he'll probably tell me he has no idea!
