Question

1. the graph below represents the amount of money earned over time, in days, at brownies bakery. based on the graph, which statements are true. select all that apply. a. the point (0,0) means when the store is open for 0 days 0 dollars are earned. b. the point (7,2100) means the store earns 7 dollars when it is open for 2100 days. c. the point (1800,6) means when the store is open for 6 days, 1800 dollars are made by the store. d. the point (5,1500) means when the store is open for 5 days, 1500 dollars are made by the store. create an equation to represent the total

Explanation:

Step1: Analyze the meaning of points on the graph

In a graph representing money earned over time, the x - axis represents time (days) and the y - axis represents the amount of money earned. For a point \((x,y)\), \(x\) is the number of days the store is open and \(y\) is the amount of money earned.

Step2: Evaluate option a

The point \((0,0)\) means when \(x = 0\) (store is open for 0 days), \(y=0\) (0 dollars are earned). This is correct as if the store is not open, no money is made.

Step3: Evaluate option b

The point \((7,2100)\) means when \(x = 7\) (store is open for 7 days), \(y = 2100\) (2100 dollars are earned). But it is incorrect to say the store earns 7 dollars when open for 2100 days. The correct interpretation is the store earns 2100 dollars when open for 7 days.

Step4: Evaluate option c

The point \((1800,6)\) would mean when \(x = 1800\) (store is open for 1800 days) and \(y = 6\) (6 dollars are earned). But this is a mis - interpretation. Also, the scale of the graph does not support such a point. The correct way to read points on this graph is \(x\) as days and \(y\) as money earned.

Step5: Evaluate option d

The point \((5,1500)\) means when \(x = 5\) (store is open for 5 days), \(y=1500\) (1500 dollars are earned). This is a correct interpretation of the point on the graph.

Answer:

a. The point \((0,0)\) means when the store is open for 0 days 0 dollars are earned.
d. The point \((5,1500)\) means when the store is open for 5 days, 1500 dollars are made by the store.
