Question

A delivery truck weighs 5.5 tons before it is loaded with packages. Once the delivery truck is full of x packages it weighs 6.1 tons. Each package in the truck weighs 0.0075 tons.

How many packages are on the truck?

Answer 1

there are total 80 packages are on the truck.

Step-by-step explanation:

weight of the car + weight of the packages = total weight when car filled

5.5 tons + x ( 0.0075 tons ) = 6.1 tons

0.0075x = 6.1 tons - 5.5 tons

0.0075x = 0.6 tons

x = ( 0.6 tons ) / ( 0.0075 )

x = 80 packages
