Kara finds the value of  x. her work is shown below. step 1      14/72 = 12/xstep 2      14x = (72) (12)step 3        14x = 864step 4        x = 61.7 mileswhat is kara’s first error? kara should have written the proportion in step 1 as  12/72 = 14/x. kara should have written the cross-product in step 2 as  12x = (72) (12).kara did not correctly divide 864 by 14 going from step 3 to step 4.kara did not find the correct product of 72 and 12 going from step 2 to step 3.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
