Part 1: Write an expression for the following real-world situation. If Mr. Jackson earns $1000 for every used car he sells and $2000 for every new car he sells, how much would he make if he sold "u" used cars and "n" new cars? Part 2: Write a real-world situation of your own and a VARIABLE expression to go with it.

    for this problem we'll start by making two equations, one that represents money made from used cars, and another that represents money made from new cars

    so for every used car that Mr J sells he makes $1000, so if he sells two used cars he will make two times that amount, if he sells three he will make three TIMES that amount, so if he sells u amount of cars, he will make u times $1000

    so our first equation looks like this (number of used cars) times $1000 = amount of money made

    good so our second equation is the same thing but with new cars, the number of new cars times $2000 equals the amount of money he makes (number of new cars) x $2000 = amount of money made from new cars

    so we have two equations \[u \times $1000 = m1\] and \[n \times $2000 = m2\]

    ok so now we need to make a third equation, m1 + m2 = T (amount of money from used cars) + (amount from new cars) = (total amount of money)

    we then substitute the first two equations into the third to make (u x 1000) + (n x 2000) = T

    and that's your equation, does that make sense?
