    Answer:

    7 cars

    Step-by-step explanation:

    The computation of the number of cars to be filled is shown below:

    A car that is 90% full and the total people is 20 so 90% would be

    = (.90)(20)

    = 18

    A car that is 65% full and the total people is 20 so 65% would be

    = (.65)(20)

    = 13

    Now

    Total number of people = (5)(18) + (3)(13).

    = 129

    Now the number of cars to be filled is

    = 129 ÷ 20

    = 6.45

    = 7 cars
