Suppose the value of z varies from a tob. There are at least two ways of thinking about what percent a changed by. We'll explore two of them herc. For each of the following questions, write an expression in terms of a and b to answer the question. a. Method 1 i. b is how many times as large as a? times as large Preview ii. Therefore, b is what percent of a? % Preview iii. Hencc, if a varies from z -a to zb, r changes by what percent? % Preview b. Method2 i. If z varies from z a to z = b, how much did z change by? Preview ii The amount z changed by (Δε) is how many times as large as the initial value, z-a? times as large Preview iii. Hence, if a varies fromx -a to zb, what is the percent change in r? 1% Preview Notice that your answers to parts (iii) of both (a) and (b) are algcbraically cquivalent! (You can rewrite cither one in the form of the other.) Submit
