A bundle of shingles weigh ~ 80lbs, so it depends if you are using 3-tab or architectual shingles. There are usually 22 shingles in a bundle of arch. and 26 in a bundle of 3-tab. Doing the division and arch shingle weighs ~3.63 lbs and a 3-tab weighs ~3.08lbs. The weight will very depending on the brand and style of shingle as well... Hope that helps you...
A standard 3-tab shingle bundle typically contains about 33 square feet of coverage. To calculate the starter needed, you generally require one starter strip for every three bundles of shingles. Thus, you would typically use about 11 feet of starter per bundle, translating to approximately 33 feet of starter for a full bundle of 3-tab shingles.

Shingles are rated in pounds / 100 square feet. Typical ratings are 235# or 265#. 1 bundle of shingles covers 1/3 of 100 sq feet. 235# shingle / 3 = 78.33 lbs
Depending on which manufacturer of starter shingles you prefer, you will get 100 linear feet, give or take a couple of feet for some brands. If using 3-tab shingles as a starter shingle, you will get roughly 78 linear feet per bundle.
