Question

Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.

Which sketch represents this situation?



a) A graph in the first quadrant containing a line segment. The x axis is labeled Days and the y axis is labeled Pages remaining. The endpoints of the line segment are begin ordered pair 0 comma 400 end ordered pair and begin ordered pair 25 comma 0 end ordered pair.

b) A graph in the first quadrant containing a line segment. The x axis is labeled Days and the y axis is labeled Pages remaining. The endpoints of the line segment are begin ordered pair 0 comma 16 end ordered pair and begin ordered pair 400 comma 0 end ordered pair.

c) A graph in the first quadrant containing a line segment. The x axis is labeled Days and the y axis is labeled Pages remaining. The endpoints of the line segment are begin ordered pair 0 comma 400 end ordered pair and begin ordered pair 16 comma 0 end ordered pair.

d) A graph in the first quadrant containing a line segment. The x axis is labeled Days and the y axis is labeled Pages remaining. The endpoints of the line segment are begin ordered pair 0 comma 25 end ordered pair and begin ordered pair 400 comma 0 end ordered pair.

Answer 1

The answer is the triangle that has points (0, 400) and (16,0)

good luck!

Answer 2

Given that Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.

The number of days it takes him to finish the book is given by 400 / 25 = 16 days.

In 0 days, he has 400 pages remaining and in 16 days he has 0 pages remaining.

Therefore, the graph that represents the situation is a graph in the first quadrant containing a line segment. The x axis is labeled Days and the y axis is labeled Pages remaining. The endpoints of the line segment are (0, 400) and (16, 0).
