To solve the exercise, you can first know how many words per minute George and Patricia can type.
*For George, you can replace x = 1 in the equation given
[tex]\begin{gathered} y=40x \\ y=40\cdot1 \\ y=40 \end{gathered}[/tex]Then, George can type 40 words per minute.
*For Patricia, you can apply the ratio with any of the rows given in the table
[tex]\begin{gathered} \frac{375\text{ words}}{5\min}=\frac{x\text{ words}}{1\text{ min}} \\ 1\min \cdot\frac{375\text{ words}}{5\min}=\frac{x\text{ words}}{1\text{ min}}\cdot1\min \\ 75\text{ words = x} \end{gathered}[/tex]Then, Patricia can type 75 words per minute.
Now, you have
[tex]\begin{gathered} \text{Words that Patricia can type - words that George can type} \\ 75-40=35 \end{gathered}[/tex]Therefore, the correct answer is A. because Patricia can type 35 more words per minute than George.
