A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the
maxonik [38]

The students rented 4 small cars and 8 large cars.

Step-by-step explanation:

Given,

Number of people in small car = 4

Number of people in large car = 7

Total people in both type of cars = 72

Let,

x represent the number of small cars rented.

y represent the number of large cars rented.

According to given statement;

4x+7y=72     Eqn 1

y = 2x           Eqn 2

Putting value of y from Eqn 2 in Eqn 1

4x+7(2x)=72\\4x+14x=72\\18x=72

Dividing both sides by 18

\frac{18x}{18}=\frac{72}{18}\\x=4

Putting x=4 in Eqn 2

y=2(4)\\y=8

The students rented 4 small cars and 8 large cars.
