Questions: A company orders boxed lunches from a deli, which all cost the same price. The relationship between the number of boxed lunches ordered, x, and the total cost in dollars of the lunches, y, is represented by a graph drawn in the xy-plane.
If the point (9,108) lies on the graph, what does the ordered pair ( 9,108 ) indicate?
9 lunches that cost 108.00 each
108 lunches that cost a total of 9.00
108 lunches that cost 9.00 each
9 lunches that cost a total of 108.00
Transcript text: A company orders boxed lunches from a deli, which all cost the same price. The relationship between the number of boxed lunches ordered, $x$, and the total cost in dollars of the lunches, $y$, is represented by a graph drawn in the xy-plane.
If the point $(9,108)$ lies on the graph, what does the ordered pair ( 9,108 ) indicate?
9 lunches that cost $\$ 108.00$ each
108 lunches that cost a total of $\$ 9.00$
108 lunches that cost $\$ 9.00$ each
9 lunches that cost a total of $\$ 108.00$
Solution
Solution Steps
The point \((9, 108)\) on the graph indicates that when 9 boxed lunches are ordered, the total cost is $108.00. This means that 9 lunches cost a total of $108.00.
Step 1: Identify the Given Values
We are given the point \((9, 108)\) on the graph, which indicates:
\(x = 9\) (number of boxed lunches)
\(y = 108\) (total cost in dollars)
Step 2: Calculate the Cost per Lunch
To find the cost per lunch, we use the formula:
\[
\text{cost per lunch} = \frac{y}{x}
\]
Substituting the given values:
\[
\text{cost per lunch} = \frac{108}{9} = 12.0
\]
Final Answer
\(\boxed{9 \text{ lunches that cost a total of } \$108.00}\)
