Use the image to answer the question.

A line graph shows number of items on the x-axis and cost in dollars on the y-axis. The graph shows the trends for A, B, C, and D. The x-axis ranges from 0 to 7 in increments of 1. The y-axis ranges from 0 to 35 in increments of 5. A line starts at the origin and passes through the plotted point A at left parenthesis 1 comma 25 right parenthesis. A line starts at the origin and passes through plotted point B at left parenthesis 2 comma 30 right parenthesis. A line starts at the origin and passes through plotted point C at left parenthesis 2 comma 20 right parenthesis. A line starts at the origin and passes through plotted point D at left parenthesis 4 comma 20 right parenthesis.

Talia noticed a sale at her favorite store. The points on the graph show how many items she bought of each. T-shirts were selling for $5 each, long sleeve shirts were $10 each, jeans were discounted to $15 each, and sweaters were on sale for $25 each.

The point corresponding to the number of pairs of jeans Talia purchased is D.

To determine which point corresponds to the number of pairs of jeans Talia purchased, we need to examine the y-coordinate of each plotted point on the graph. The y-coordinate represents the cost of the items. Since jeans were discounted to $15 each, we need to identify the point that has a y-coordinate of 15.

Looking at the given graph, we can see that the point that has a y-coordinate of 15 is point C, plotted at (2, 20). This means that Talia purchased 2 pairs of jeans.

Therefore, the point corresponding to the number of pairs of jeans Talia purchased is C.
