Question

Ron Sue are planning a weeding and have been quoted some prices by the banquet facility. If they invite 50 guest, it will cost $4750. If they invite 100 guest, it will cost $9000. There is a linear relationship between the number of guests the cost. The banquet facility can hold a maximum of 250 guests.

1. Identify the independent and dependent variable in this situation. Label them with smart variables and include units.

Answer 1

C = a + bN

Where, N, the number of guests is the independent variable.

and C is the dependent variable.

Step-by-step explanation:

At the wedding if 50 guests are invited then the total cost will be $4750 and if 100 guests are invited then the total cost will be $9000.

Therefore, it is clear that the number of guests invited is the wedding is the independent variable and the cost of the wedding is a dependent variable.

If we consider the number of guests invited is N and the total cost of the wedding is C, then there will be a linear relationship between them

C = a + bN

The values of a and b can be calculated from the data given.

The unit of C is Dollars and that N is numbers. (Answer)
