Answer:the total cost for a group of 6 is $45
Step-by-step explanation:
Let x represent the number of persons that rent the raft.
The cost to rent a raft is $7 per person. This means that if x persons rent the raft, the cost would be 7x
There is a $3 launch fee per raft. This means that the total cost of for x persons would be
7x + 3
A raft can hold up to 6 people.
If a group of 6 persons rent the raft, the total cost of renting the raft would be
7 × 6 + 3 = 42 + 3 = $45
