From the given values, we can see that option 8 (The number of brochures is 50, and the total cost is $630) is the only one that is correct based on the linear relationship between the number of brochures and the total cost.
To determine which statement is true about the relationship between the number of brochures and the total cost of printing, we need to analyze the given information.
The given table provides data for the number of brochures and the total cost of printing, including the printing fee. Let's examine the table:
Number of Brochures | Total Cost (including printing fee)
-----------------------------------------------------
40 | $600
43 | $607.50
45 | $612.50
50 | $630
55 | $637.50
By observing the table, we can determine the linear relationship between the number of brochures and the total cost. We need to find the additional fee per brochure and the printing fee.
To calculate the additional fee per brochure, we can take any two pairs of data and find the difference in the total cost between them, divided by the difference in the number of brochures. Let's consider the first and second entries:
Additional fee per brochure = (Total Cost for 43 brochures - Total Cost for 40 brochures) / (43 brochures - 40 brochures)
= ($607.50 - $600) / (43 - 40)
= $7.50 / 3
= $2.50
From this calculation, we find that the additional fee per brochure is $2.50. Therefore, the statement "The additional fee per brochure is $2.50" is true.
To determine the printing fee, we can take any pair of data and subtract the additional fee per brochure multiplied by the number of brochures from the total cost. Let's consider the first entry:
Printing fee = Total Cost for 40 brochures - (Additional fee per brochure * 40 brochures)
= $600 - ($2.50 * 40)
= $600 - $100
= $500
From this calculation, we find that the printing fee is $500. Therefore, the statement "The printing fee is $250" is false.
Based on the calculations, the correct statement is "The additional fee per brochure is $2.50."
