Chapter 1.9, Problem 43MR

To determine

Find the number of more cars and trucks were flex-fuel in 2016.

Answer to Problem 43MR

  $\text{N}=20,000,000-5,000,000$

Explanation of Solution

Given:

In 2004, approximately 5 million cars and trucks were classified as flex − fuel. In 2016 that number increased to about 20 million.

Concept Used:

Number of Trucks and Cars increased to about 20 million and in 2004 it was 5 million. This means 2016 the number of trucks and cars are much more than in 2004.

5 million = 5,000,000 and 20 million = 20,000,000.

Number of increased cars and Trucks and cars in 2016 is the difference between the number of trucks in 2016 and 2004.

Calculation:

Number of Trucks and cars in 2004 = 5,000,000

Number of Trucks and cars in 2016 = 20,000,000 Let the number of Trucks and cars increased in 2004 to 2016 is N

Number of increased cars and Trucks and cars in 2016 = Number of Trucks and cars in 2016 - Number of Trucks and cars in 2004

Equation: $\text{N}=20,000,000-5,000,000$

Thus, the required equation is $\text{N}=20,000,000-5,000,000$
