They know that 1.14% of the cases must be rejected because at least one bottle was damaged in the production line. a. Express the percent as a rate per 100. b. Write and solve a proportion to find how many cases are rejected each hour during production. = X__ 1200 b) 100x = 2280 X = 22.8 About 23 cases
