Sunscreen Calculator

Formula

The formula to calculate the amount of sunscreen needed (SS) is:

\[ SS = (A \times 1.5 + C \times 1) \times D \]

Where:

\( SS \) is the ounces of sunscreen needed for the trip (oz).
\( A \) is the number of adults.
\( C \) is the number of children.
\( D \) is the number of days of the trip.

Example

Let's say there are 2 adults and 3 children going on a 5-day trip. Using the formula:

\[ SS = (2 \times 1.5 + 3 \times 1) \times 5 \]

We get:

\[ SS = (3 + 3) \times 5 = 6 \times 5 = 30 \]

So, the amount of sunscreen needed (\( SS \)) is 30 oz.

What is Sunscreen Needed?

The amount of sunscreen needed is a calculation that determines how much sunscreen you should bring for a trip based on the number of adults, children, and the duration of the trip. This helps ensure you have enough sunscreen to protect everyone from sun exposure.
