Question

The image is a line graph titled "Money Spent at Gift Shop" that illustrates the relationship between the Amount Spent and the Number of People who spent at least that amount.

Here's a detailed description of the graph:

X-axis (Horizontal): Labeled "Amount Spent," this axis shows the money spent in increments of 20, ranging from 0 to 220.

Y-axis (Vertical): Labeled "Number of People," this axis shows the count of people in increments of 20, ranging from 0 to 120.

Trend: The line clearly shows a negative correlation, meaning as the Amount Spent increases, the Number of People who spent that amount or more decreases. This is a common pattern in purchasing data.

Key Data Points:

At an amount of $20, 100 people spent at least that much.

At $40, 82 people spent at least that much.

At $100, 70 people spent at least that much.

At $200, only 30 people spent at least that much.
About how many people spent $250 at the gift shop?

Answer 1

10

Reason: From $100 to $200 the count falls from 70 to 30 (a drop of 40 people over $100, i.e. 0.4 people per dollar). Extrapolating another $50 to $250 gives a drop of 20 people, so 30 − 20 = 10 people.
