The mathematical equations to determine the price of daily tooth brushing 3x day are completed in the following steps for the toothpaste:

Step1: Toothpaste Tube in ml / 0.17 gram of toothpaste = Total number of toothbrushes from one tube of toothpaste.

Step 2: If the person brushes 3 times per day: then take the total number of brushes from Step 1 and divide this by 3x day = number of days of the patient brushes 3x a day. For the tablet formats is the number of tablets / 3 to get a daily rate.

Step 3: The price of the Toothpaste in Rand / number of 3x brushes per day from one tube (step 2) = cents per day to brush 3xday. For the tablet formats Rand price / step 2 = cents per day to brush 3xday.
