Answer:

Step-by-step explanation:
Let's set up a proportion using the following setup.

We know 30 buses can carry 1,500 people.

We don't know how many people 5 buses can carry, so we say 5 buses carry x people.


Cross multiply. Multiply the numerator of the first fraction by the second fraction's denominator. Then, multiply the first denominator by the second numerator.

Solve for x. It is being multiplied by 30. The inverse of multiplication is division. Divide both sides by 30.

5 buses can carry 250 people.
158, because due to PEMDAS you would do all the functions in the parenthesis first, then you would move on to multiplication, and finally you would find the sum of the equation
