Question

The graph shows the amount of money that Emma spends, $y$ (in $\$$) over time,
$x$ (in days). What does the point $(4,100)$ represent?

• A. Emma does not spend $\$100$ in $4$ days.
• B. Emma spends $\$40$ in $10$ days.
• C. Emma spends $\$4$ in $100$ days.
• D. Emma spends $\$100$ in $4$ days.

Answer 1

The correct option is D Emma spends $\$100$ in $4$ days.

For the point $(4,100)$ or $(x,y)$:
$4$ represents $\left(x\right)$ the number of days.
$100$ represents $\left(y\right)$ the amount of money spent (in $\$$).
Thus, point $(4,100)$ represents that the amount spent in $4$ days by Emma is $\$100$.
