Pls help i want to understand how to do this homework Last week, you wrote an equation for Kateri, who was saving quarters and dimes to reach a goal of $10 (1,000 cents). One equation that relates this situation is . Suppose Kateri collects 70 coins to reach her goal.

1a. What equation relates x and y to the total number of coins Kateri collects.



1b. Graph both Equations on the same grid using Desmos, the TI on your desktop, or by hand. Insert a picture of your graph showing the intersection point of the lines.

1c. What is the intersection point? (x. y)

1d. Explain what the coordinates of the intersection point tell you about this situation.

Students in Eric’s gym class must cover a distance of 1,600 meters by running or walking. Most students run part of the way and walk part of the way. Eric can run at an average speed of 200 meters per minute and walk at an average speed of 80 meters per minute. Eric completes the 1,600 meters in 12 minutes.

2a. Write an equation for the 1,600 meters Eric will cover if he runs for x minutes and walks for y minutes.

2b. Write an equation that relates running time x and walking time y to his total time (12 minutes).

2c. Graph both Equations on the same grid using Desmos, the TI on your desktop, or by hand. Insert a picture of your graph showing the intersection point of the lines.

2d. What is the intersection point? (x, y)

2e. Explain what the coordinates of the intersection point tell you about this situation.
