1. The problem statement, all variables and given/known data Jeffrey is planning a large dinner party. His budget is $3000. He has the option of serving chicken at $30 per meal or roast beef at $40 per meal. The cost of the party can be modeled with the equation 30c + 40b = 3000, where c represents the number of chicken meals ordered and b represents the number of roast beef meals ordered. What are the restrictions on the variables? Justify your reasoning. 2. Relevant equations restrictions on variables. 3. The attempt at a solution Well for the variable c you cannot exceed 100 meals or you will exceed your budget and you cannot have – 1 or more meals/$. So it has to be 0 or greater. So you can say: 0 <_ C <_ 3000 ($) (Note: the <_ is meant to represent greater or equal to.) Same with b you cannot exceed 75 beef meals or you u will exceed your budget. You also can’t have –1 meals or dollars. So we can say that it has to be 0 or greater. 0 <_ B <_ 3000 ($) Its a new concept for me and I would like to know if I am understanding it correctly, and got the answer right. I appreciate your time and effort and would like to say thank you in advance.
