Four bundles of design(architecture) to 100sq = 48 bundles
Three bundles of three tab to 100sq = 36 bundles
The surface area of a roof is measured in "squares" of shingles. Each square covers 100 square feet. However, when you buy shingles, they're usually priced per bundle.
Calculate the number of bundles needed by measuring the roof's square footage (length X width). Divide that number by 100 to get the number of squares needed. Multiply the number of squares by 3 (in most cases) or the number of bundles it takes to equal one square. Again, in most cases 3 bundles = 1 square.
If I recall from my roofing days, a square is 3 bundles of shingles. Those 3 bundles cover 100 of square feet.
9 bundles assuming std. 3 bundle/sq. shingles
A 'bundle' is an arbitrary amount - Usually we talk about 'squares' in roofing. One 'square' is 100 square feet
4 bundles of shingles covers 100sq.ft. of course this is approx. shingles come in several sizes and then you must allow for waste cuts etc
How much dose 3 square of roofing cover

9 bundles assuming std. 3 bundle/sq. shingles
Not sure, but one bundle covers 33.33 square feet. 3 bundles to a square.

A bundle of Shingles will cover roughly 33 square feet. A square of Shingles (3 Bundles) will cover 100 square feet.
How much dose 3 square of roofing cover
How many bundles of 3-Tab Shingles are needed to cover 80 square feet?
How much area would 15 bundles of shingles cover. Standard duty shingles use 3 bundles for every 100 square feet so 15 bundles would cover 500 square feet.

If your shingles say they cover 3 bundles to a square ( 10'x10' or 100 sq. ft) then one and a half. Some thicker, heavier shingles are 4 bundles to a square so you'd need 2.
When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.
