    Trump stamps sold at $1.25 and Obama stamps sold at $2 . How many of each stamp was sold if 700 stamps were sold making $1250

    Let o be the number of Obama stamps. Let t be the number of Trump stamps. We have two equations:
    1. o + t = 700
    2. 2o + 1.25t = 1250
    Using our simultaneous equations calculator, we get:
    o = 500
    t = 200
