Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.

Given:

The equation is

where, y is the number of cars and x is the number of trucks shipped.

To find:

The number of trucks that can be shipped if there are no cars.

Solution:

We have,

If there are no cars in the cargo ship, then y = 0 because y is the number of cars.

Putting y=0 in the given equation, we get

Divide both sides by 7.5.

x is the number of trucks shipped.

Therefore, the number of trucks that can be shipped if there are no cars is 2880.

you never say the total so we cant find the percentage used for petrol
