Question

Mrs. Jacobson asked her students to write a word problem that describes the graph below.

A graph has days on the x-axis and money on the y-axis. A line goes through points (0, 8) and (4, 0).

Which word problem accurately describes the graph?
Jamie has $8, and she pays $2 per day to ride the bus.
Melinda has $4 and earns $2 allowance per day doing chores.
Carrina has $8, and she earns $2 per day babysitting.
Louise has $4, and she pays $2 per day for school lunch.
Mark this and return

Answer 1

Carrina has $8, and she earns $2 per day babysitting.

Explanation:

The graph has days on the x-axis and money on the y-axis, so we know the word problem should involve a person earning or spending money over a period of time.

The line goes through the points (0, 8) and (4, 0). This means that at time 0 (the beginning), the person has $8, and at time 4 (the end), the person has $0.

Of the four given word problems, only one involves a person starting with $8 and ending with $0 after 4 days: "Carrina has $8, and she earns $2 per day babysitting."

Therefore, "Carrina has $8, and she earns $2 per day babysitting" accurately describes the graph.

Answer 2

Explanation:

"Carrina has $8, and she earns $2 per day babysitting." This word problem describes a situation in which the amount of money (represented on the y-axis) decreases by $2 each day (represented on the x-axis), which matches the slope of the line on the graph. The problem also specifies that Carrina has $8 at the beginning, which matches the starting point of the line on the graph.
