A serum is being given to a patient to desensitize the patient for allergies. Each week the dosage is increased by 0.01 centiliters (cL). If the patient receives 0.5 milliliters (mL) the first week, what dosage in milliliters (mL) would be received in the eighth week?

Let’s analyze the problem:

A patient is given a serum for an allergy.

The serum increased 0.01 cl or equivalent to. 1 ml every week.

For the 1st week, patient received. 5ml of serum.

Now, we need to find the total amount of serum given in the 8th week

1st week =.5 ml

2nd week =.5 +.1 =.6ml

3rd week =.6 +.1 =.7ml

4th week =.7 +.1 =.8ml

5th week =.8 +.1 =.9ml

6th week =.9 +.1 +.10ml

7th week =.10 +.1 =.11ml

8th week =.11 +.1 =.12 ml

Thus, in the 8th week, a patient received. 12ml of serum.
