d. Write and simplify an expression for the total cost of six friends to go to the museum if only four friends view the mummy exhibit.

To find the total cost of six friends going to the museum if only four friends view the mummy exhibit, we need to consider the cost of admission for each friend and the cost of viewing the mummy exhibit for the four friends who choose to do so. Let's denote the cost of admission for each friend as \( C \) and the cost of viewing the mummy exhibit as \( M \). The total cost for six friends to go to the museum can be expressed as: \[ \text{Total Cost} = 6C + 4M \] This expression represents the total cost of admission for all six friends plus the cost of viewing the mummy exhibit for the four friends who choose to do so. Now, let's simplify this expression. Simplify the expression by following steps: - step0: Solution: \(6C+4M\) The simplified expression for the total cost of six friends going to the museum if only four friends view the mummy exhibit is \(6C + 4M\).
