Depends on the brand and model - shingles come 3, 5, 6 and 7 tab (at least) and also continuous tabbed strip, as well as architectural (overlapping tab) designs - and there is manufacturer recommended reveal (the amount of the tab that sticks below the next higher row) and variations on that (more when a contractor is cheating to use less materials, more in severe wind environments to reduce tha risk of tab lifting), so the number of shingles to cover a specific area can vary by a factor of maybe as much as 2 fold between the different options.

And the number of bundles needed to cover a particular area varies too - depending on size of shingles, thickness, etc - I have seen heavyweight hail and arctic shingle bundles with as few as 12-15 shingles in a bundle, and cheapo paper-thin shingles with as many as about 40 in a bundle. A bundle can also weigh from about 40 to as much as about 80 pounds per bundle, though there is a trend to keep them to not more than 70 pounds to conform to OSHA lifting standards.

So you should be looking at the number of shingles needed for the chosen brand and model and reveal dimension, to cover your particular area. Many normal weight shingles come 3 or 4 bundles per square at recommended exposure (a square is 100SF of roof coverage), with 22 to 29 "standard" 3-tab shingles per bundle - but do not count on that without checking.

If you are talking only field coverage - 40x50 feet with no starter or ridge shingles or valleys, that is 2000 SF so 20 squares worth of shingles with zero wastage or cutoffs.

Here are a couple of more in-depth previous question about shingle coverage FYI - and don't forget there is a difference in "coverage" and "demand" - how many shingles it actually takes to do a roof including starter row, ridge shingles, angle/valley cuts and cutoff waste, etc.
