If 20 pounds of fertilizer will cover 1,500 square feet of lawn, how many pounds are needed for 2,650 square feet? (Round your answer to the nearest thousandth.)

Question

anonymous · Answer

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.
