    Number of times to change fluid = 3

    Step-by-step explanation:

    The amount of fluid that needs to be changed is 7.5 quarts.

    The fluid can only be removed and replaced 2.5 quarts at a time.

    How many 2.5 quart changes do we need to have 80% or more new fluid?

    Lets first find out the 80% amount of the fluid that needs to be changed.

    80% amount of fluid = 0.80*7.5

    80% amount of fluid = 6 quarts

    Now let us find out the number of times required to change the fluid.

    Number of times = 6 quarts/2.5 quarts

    Number of times = 2.4

    We cannot have number of times in fraction so we can either go with 2 times or 3 times, since 2 times is not enough to make 80% or more new fluid, we must change the fluid 3 times, therefore the required number of times to change the fluid is

    Number of times to change fluid = 3
