Question

A wedding planner caters for wedding receptions. He charges R960 for the use of the venue and R 260 per person for a meal. 

Write a formula relating the cost of the function to the number of guests. Using your formula, evaluate the total cost for 120 people at the wedding.

Answer 1

Let cost be C(x)

x be value paid.

So, C(x) = 260x + 960

Thus, above is the cost function for number of guests.

Given x = 120

C(120) = 260*120 + 960

C(120) = 32160

Hence, the total cost for 120 people at the wedding is R32160
