Keith and his friends are heading to the Thunder Beach water park. They plan to purchase the group package, which costs \( \$ 78 \) for 6 people. That's \( \$ 3 \) less per person than the normal cost for an individual. What is the normal cost for an individual?

Let's determine the normal individual cost step by step. 1. **Let \( x \) be the normal cost per individual.** 2. **Group Package Cost per Person:** - The group package costs \$78 for 6 people. - Therefore, the cost per person in the group package is: \[ \frac{78}{6} = \$13 \text{ per person} \] 3. **Relationship Between Group and Individual Cost:** - The group package is \$3 cheaper per person than the individual cost. - So, we have: \[ x - 3 = 13 \] 4. **Solve for \( x \):** \[ x = 13 + 3 = 16 \] **Therefore, the normal cost for an individual is \$\boxed{16}.**
