It takes 5 people to lift a car and twice as many people to lift a truck. How many people are needed to lift 6 cars and 3 trucks?
Let's think step by step below.
60
It takes 5 x 2 = 10 people to lift a truck.

5 x 6 = 30 people are needed to lift the cars.

10 x 3 = 30 people are needed to lift the trucks.

Altogether, 30 + 30 = 60 people are needed.
