Paolo solved an inequality and graphed the solution on the number line. Which of the following solutions did he graph?
a. 2.8x<10.5
b. 4.9x>19.6
c. 3.7x>14.8
d. 2.1x<8.4
The solution that Paolo graphed would have an arrow pointing towards the smaller values on the number line.
Thus, the correct answer is:
d. 2.1x<8.4
