Ответ:
48 persons will hire 4-seater cars = 3, and 9-seater cars = 4.
Step-by-step explanation:
Let the people hire 4-seater cars = x
and number of 9-seater cars hired by the people = y
Total number of seats in cars = 4x + 9y
Since number of persons planning to travel = 48
So, 4x + 9y = 48
Now we will randomly plug in the values of x and y to get the numbers of cars hired.
For x = 1 , y =
, Not possible.
for x = 2, y =
, Not possible
for x = 3, y = 4
Therefore, 48 persons will hire 4-seater cars = 3, and 9-seater cars = 4.
