Cost of a Tour.

Question

The cost, in dollars, for Crescent City Tours to provide a tour for x people can be determined by the expression 220 + 2.75x. Determine the cost for Crescent City Tours to provide a tour for 75 people.

Answer 1

Solving this problem is a matter of substitution.

 

They have given you a rule for finding total cost of a tour:  220 + 2.75x

 

They have defined a variable:    x = number of people

 

To determine the cost of a tour for 75 people, you would substitute 75 for the variable x:  220 + 2.75(75)

 

Multiply first, then add the 220 and you will have your answer!
