The answer is C. People with lower incomes tend to purchase more services, which are rarely subject to sales tax.

Step-by-step explanation:

Lower-income households spend a greater share of their income than higher-income households do. The burden of a retail sales tax is regressive when measured as a share of current income: the tax burden as a share of income is highest for low-income households and falls sharply as household income rises. The burden of a sales tax is more proportional to income when measured as a share of income over a lifetime. Even by a lifetime income measure, however, the burden of a sales tax as a share of income is lower for high-income households than for other households: a sales tax (like any consumption tax) does not tax the returns (such as dividends and capital gains) from new capital investment and income from capital makes up a larger portion of the total income of high-income households.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
