Q. A corporate team-building event costs $23, plus an additional $5 per attendee. Is the total cost directly proportional to the number of attendees?Choices:(A)yes(B)no
Identify Components: Identify the components of the cost equation.The total cost for the event is made up of a fixed cost and a variable cost that depends on the number of attendees.
Write Equation: Write the equation for the total cost.Total cost = Fixed cost + (Cost per attendee × Number of attendees)Let C be the total cost and n be the number of attendees.C=23+5n
Analyze Proportionality: Analyze if the cost is directly proportional to the number of attendees. Direct proportionality means that as one quantity increases, the other quantity increases at a constant rate. Here, the cost per attendee is constant (5),butthereisalsoafixedcost(23) that does not change with the number of attendees.
Consider Fixed Cost: Determine if the presence of the fixed cost affects direct proportionality.Since there is a fixed cost, the total cost is not solely dependent on the number of attendees. This means the relationship is not a direct proportion because of the additional fixed cost.
