Help! Why do I suck at word problems so much :( I am good with equations and stuff, but when I stare at a word problem I suffer because I don't know how to set up the equation!!!

    Wendy, a loan officer at a bank, has $1,000,000 to lend and is required to obtain an average return of 18% per year. If she can lend at a rate of 19% or at the rate of 16%, how much can she lend at the 16% rate and still meet her requirement? I've been staring at this problem for half an hour and I don't even know where to start!

    you have to start by making a variable to represent what you are trying to find write it out (spend the ink)

    Let x = amount loaned at 16%.

    would write "let \(x\) be the amount lent at 16%"

    then since the total lent is one million, the amount lent at 19% must be what?

    ok let me ask you this suppose you invest $400,000 at 16% what gets invested at 19%?

    let me ask again the total is one million you invest 400,000 at 16% how much is left to invest at 19%?

    after you do it with 400,000 we can do it with 700,000 and with 20,000 so we understand what we are doing and it is not so mysterious

    ok i will give an example i have a million dollars to invest (yeah right) i invest $200,000 at 16% that leaves me with $800,000 to invest at 19% clear?

    yay now lets cut to the chase you invest \(x\) at 16% how much do you have left to invest at 19%? your answer must have an x in it

    ok good in summery ( we are not done) you invest \(x\) at 16% and that leaves you \(1,000,000-x\) so invest at 19% next...

    ok so now how much do we make on the \(x\) dollars? 16% so we need to write 16% of x in math that is \[.16x\]

    on account of 16% means 0.16 and "of" means \(\times\) clear?

    hint, it is going to look a lot like \(.16x\) only with \(.19\) instead of \(.16\) and \(1,000,000-x\) instead of \(x\)

    just put a plus sign between the two expressions

  44. steve816

    So add the 2 expressions and make it equal to 180,000?

    ok it is easier to solve by multplyying both sides by 100 and solving \[16x+19(1,000,000-x)=18,000,000\]

  51. steve816
    • one year ago

    16x + 19,000,000 - 19x = 18,000,000 -3x + 19,000,000 = 18,000,000 -3x = -1,000,000 x = 333,333.33
