A cable car can safely carry n people thete are alreafy 3/4n people on the cable car only 12 more people can board the cable car before it becomes unsafe. How many people can the cable car safely carry

Answer 1

Answer: 48 people.

Step-by-step explanation:

1. You know that $n$ represents tha number of people that the cable car can safely carry.

2. If you know that there are $\frac{3}{4}n$ and only 12 more people can board it before it becomes unsafe, you can write the following expression:

$n=\frac{3}{4}n+12$

3. Now, you must solve for $n$.

4. Then, the number of people that the cable car safely carry is:

$n-\frac{3}{4}n=12\\\frac{1}{4}n=12\\n=12*4\\n=48$
