Suppose the value of a varies from a = a to x = b. There are at least two ways of thinking about what percent a changed by. We'll explore two of them here. 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. Hence, if varies from a = a to x = b, changes by what percent? % Preview b. Method 2 i. If e varies from a = a to x = b, how much did change by? Ax = Previcw ii. The amount changed by (Ax) is how many times as large as the initial value, a = a? times as large Preview iii. Hence, if varies from a = a to x = b, what is the percent change in x? % Preview Notice that your answers to parts (iii) of both (a) and (b) are algebraically equivalent! (You can rewrite either one in the form of the other.) Submit
