Two hourglasses are turned over at the exact same time. The first hourglass contains 300 grams of sand in the upper bulb and sand flows down into the lower bulb at a rate of 5 grams per minute. The second hourglass contains 200 grams of sand in the upper bulb and sand flows down into the lower bulb at a rate of 2 grams per minute.
The system of equations below model the amount of sand remaining, y, in the upper bulbs of the hourglasses after x minutes.
First, select the point on the graph that represents the solution to the system of equations. Notice that one of the equations in the system has already been graphed.
Then, determine the approximate number of minutes it takes for the amount of sand in the top bulbs of the hourglasses to be equal.
