Question

Problem ADr. Hong prescribed 0.019 liter moremedicine than Dr. Tannenbaum. Dr.Evans prescribed o.02 liter less thanDr. Hong. Who prescribed the mostmedicine? Who prescribed the least?1

Answer 1

Let say Dr. Hong = H

Dr. Tannenbaum = T

Dr. Evans = E

Now, Dr. Hong prescribed 0.019 liters more

medicine than Dr. Tannenbaum.

It means H = 0.019 + T

Also, Dr.Evans prescribed 0.02 liters less than

Dr. Hong.

It means E= 0.02 - H

With the information before, we replace the H value on the E equation:

E= 0.02 - H

E = 0.02- 0.019 + T

E = 0.001 + T

This means that Dr. Evans prescribed 0.001 more medicine than Dr.Tannenbaum

So:

E > T, H> T and E< H

Therefore:

-Who prescribed the most medicine? Dr. Hong prescribed more medicine than Dr. Evan and Dr.Tannenbaum

-Who prescribed the least? Dr.Tannenbaum prescirbed the least medicine
