Ex 25-3 differential analysis for a discontinued product obj. 1 a condensed income statement by product line for celestial beverage inc. indicated the following for star cola for the past year: sales $390,000 cost of goods sold 184,000 gross profit $206,000 operating expenses 255,000 loss from operations $ (49,000) it is estimated that 20% of the cost of goods sold represents fixed factory overhead costs and that 30% of the operating expenses are fixed. because star cola is only one of many products, the fixed costs will not be materially affected if the product is discontinued

Some common minerals in the natural world are quartz, feldspar and mica. These 3 common rock forming minerals can occur in both sedimentary rocks like a sandstone or in a granitic rock like true granite. If they occur in a granite it quite likely formed in molten conditions deep within the earth's crust like in the depths of the zone of subduction in or near the mantle. As the molten material or magma moved up towards the surface through the crust it would cool off as it encountered cold solidified country rocks closer to the surface and then it would cool also and as it cooled the minerals would form-first the high temperature minerals like plagioclase feldspar and then progressively lower temperature minerals like orthoclase feldspars, mica and then quartz. Then, as for a sandstone, it forms from sand which  may be derived from the weathering of say a granite into its constituent minerals like quartz, feldspar and mica and then these being washed down say to the sea where they form say alluvial fans which then with the accumulated weight of overlying sediments gets converted into a rock ie a type of sandstone.
