Final answer:
When 10 bags of tortilla chips are used, a proportional calculation shows that the number of servings of nachos, n, equals 50.
Step-by-step explanation:
The question is focused on determining the number of servings of nachos, n, when given a specific number of bags of tortilla chips, c. This is a proportional relationship problem where we know that 8 bags of tortilla chips produce 40 servings of nachos. To find n when c = 10, we can set up a proportion (8/40 = 10/n) and solve for n.
First, cross-multiply: (8) * (n) = (40) * (10).
Then, divide both sides by 8 to isolate n: n = (40 * 10) / 8.
After doing the calculation, we find that n equals 50 servings of nachos when c = 10 bags of tortilla chips.
Therefore, the correct answer is option a) 50.
