Final answer:

To find the number of lymphocytes, multiply the total count of 7,742 leukocytes by the lymphocyte percentage of 36% (0.36). The result is 2,787 lymphocytes present.

Step-by-step explanation:

To calculate the number of lymphocytes present when a doctor orders 7,742 leukocytes and 36% of them are lymphocytes, you would use the following steps:

  1. First, understand that you need to find 36% of the total leukocyte count.
  2. Calculate the percentage by multiplying the total leukocyte count by the percentage of lymphocytes in decimal form (36% = 0.36).
  3. Do the math: 7,742 leukocytes x 0.36 = 2,787.12. Since you cannot have a fraction of a cell, the number of lymphocytes is 2,787.

The answer is that there are 2,787 lymphocytes present in the sample of 7,742 leukocytes.
