HURRY! Celia uses the steps below to solve the equation Negative StartFraction 3 over 8 EndFraction (negative 8 minus 16 d) + 2 d = 24.

Step 1 Distribute Negative StartFraction 3 over 8 EndFraction over the expression in parentheses.

3 minus 16 d + 2 d = 24

Step 2 Simplify like terms.

3 minus 14 d = 24

Step 3 Subtract 3 from both sides of the equation.

Negative 14 d = 21

Step 4 Divide both sides of the equation by –14.

d = StartFraction 21 over negative 14 EndFraction = Negative three-halves = negative 1 and one-half

Which corrects the error in the step in which Celia made the first error?

In step 1, she should have also distributed Negative StartFraction 3 over 8 EndFraction over 2d, to get 3 minus 16 d + (negative three-fourths d) = 24.

In step 1, she should have also distributed Negative StartFraction 3 over 8 EndFraction over –16d, to get 3 + 6 d + 2 d = 24.

In step 3, she should have added 3 to both sides of the equation to get Negative 14 d = 27.

In step 3, she should have first divided both sides by –14 to get 3 + d = 24 .

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.
