A caterer in quoting the charge for producing a dinner proposes the following terms. For a group of 60 people, he will charge $30 per person. For every extra 10 people, he will lower the price by $1.50 per person for the whole group. What size group does the caterer want to maximize his income?
Thanks in advance
this is a revenue question
let x represent any changes so set up the functions as followed:
Revenue= price x quantity
(60 + 10x)(30 - 1.50x)
expand on this then since it want you to find the max income complete the square to get your answer
hope this helped
