    Think of this problem (and more importantly, these problems overall) as a proportion. 20 lbs of fertilizer / 1500 sq ft = x lbs of fertilizer / 2650. Ignoring units, 20 / 1500 = x / 2650. Solve for x.

    Not sure why it would be wrong. I suspect the rounding, but it says nearest thousandth so 35.333 would be correct.

    thats the fractional answer... your question said round to the nearest thousandth so yea, something was wrong in the question in regards to what they were looking for.
