John has $1,600 at the beginning of his trip, after spending money, he still has exactly $800 less than he spent on the trip. How much money does John still have?
Choose the correct answer:
A) $200  B) $400  C) $600  D) $800  E) $1,200
let the money spent be x   money he is left with after spending = x-800   total money --&gt; x+(x-800) = 1600   solving for x will give x = 1200,   therefore the money he is left with = x-800   = 1200 - 800=
