To solve: for the weight of a boat with a given set of specifications
Answer to Problem 18P
The weight of the boat is
Explanation of Solution
Given Information: The statements (1) The weight of a boat is 1500 lb more than that of its motor and 1900 lb more than its trailer
(2) The sum of weights of boat and motor is 5 times that of the weight of trailer.
The given statements express the relation between weights of a boat with its motor and trailer.
Let the weight of the boat be x .
1. The first statement gives the weight of the motor and trailer in terms of the weight of the boat as
2. The second statement connects the sum of weights of boat and motor to that of the trailer as,
Solving the equation gives the weight of the boat as,
