question 7

Multiple Choice

You have collected the data for a Time-Cost CPM Scheduling model analysis.The time is in days and the project "direct costs" are given below. $\begin{array}{|l|l|l|l|l|l|}\hline & \text { Immediate } & \text { Normal } & \text { Crash } & \text { Normal } & \text { Crash } \\\hline \text { Activity } & \text { Predecessor } & \text { Time } & \text { Time } & \text { Cost (Direct) } & \text { Cost (Direct) } \\\hline \text { A } & \text { None } & 3 & 2 & \$ 300 & \$ 400 \\\hline \text { B } & \text { A } & 3 & 3 & \$ 100 & \$ 100 \\\hline \text { C } & \text { A } & 1 & 1 & \$ 200 & \$ 200 \\\hline \text { D } & \text { B and C } & 3 & 2 & \$ 400 & \$ 550 \\\hline \text { E } & \text { D } & 2 & 1 & \$ 500 & \$ 900 \\\hline \text { F } & \text { E } & 3 & 3 & \$ 200 & \$ 200 \\\hline \text { G } & \text { F } & 2 & 2 & \$ 100 & \$ 100 \\\hline\end{array}$
The indirect costs for the project are determined on a daily duration basis.If the project lasts 16 days the total indirect costs are $400,15 days they will be $250,14 days they will be $200 and 13 days they will be $100.If you crash this project by one day what is the total (i.e. ,direct and indirect) project cost?

• A)$2,150
• B)$2,300
• C)$2,400
• D)$2,450
• E)$2,500

Definitions:

Denatured

Loss of a protein’s or enzyme’s normal shape so that it no longer functions; usually caused by a less than optimal pH and temperature.

Enzyme Structurally

Refers to the three-dimensional arrangement of atoms in an enzyme, which is critical for its catalytic activity and specificity.

Cofactor

Nonprotein assistant required by an enzyme in order to function. Many cofactors are metal ions; others are coenzymes.

Inhibitor

A substance that slows down or prevents a particular chemical reaction or other process.
