6.6

Explanation

In order to determine the number of gallons that Catherine put on the hot tub, calculate the absolute value of the difference between the two endpoints.

The two endpoints are -4.8 and 1.8

So, the distance between the two red points on the number line is

[tex]\begin{gathered} =1.8--4.8 \\ =1.8+4.8 \\ =6.6 \end{gathered}[/tex]

Hence, the number of gallons catherine put in the hot tub is 6.6 gallons
