解释：

To achieve 6% EBITDA growth with only 1% revenue growth, Benrich will need to achieve cost-cutting strategies related to the cost of goods sold and selling, general, and administrative expenses. The growth rates of both expense items must be below 1% to ensure improved EBITDA margins. To illustrate the margin assumptions necessary, assume Benrich’s revenues grow from 1 to 1.01 (i.e., 1% growth). Benrich’s EBITDA on revenue of 1 is 0.20, and 6% growth would reflect an increase in EBITDA from 0.20 to 0.212. Thus, the EBITDA margin required would be 20.99% (= 0.212 ÷ 1.01). Thus, the combined COGS and SGA expenses would need to decline from 80% of revenues (i.e., 100%−20%) to 79.01% in the first year. The combined COGS and SGA would be equal to 0.798 (= 1.01 − 0.212), and this represents a 25-basis point decline in costs from year to year. This pattern of declining costs would need to continue at slightly increased rates during each subsequent year over a multi-year time horizon to achieve the goal.
