Question

Nadim is hosting a party and is hiring a catering company to make and serve the food. The caterer charges a flat fee for serving the food plus a per person rate for the meals. If the equation used to calculate the total cost of Nadim's party is $y=11x+300$, then which of the following most likely represents the number of people attending the party

• A. x
• B. y
• C. 11
• D. 300

Answer 1

The correct option is A x

The cost for Nadim's party is given by $y=11x+300$.

This cost comprises of a flat fee and a per person rate for meals.

By looking at the above equation, we conclude that $300$ represents the flat fee (as it does not depend upon any other variable), whereas $11x$ represents the cost of meals. This allows us to conclude that, most likely, the per person cost of meals is $11$ and number of people attending Nadim's party is $x$.
