question

As the chief financial officer for the Feynman electric vehicle company, Jill often reviews the company's revenue for each of its 4 vehicle models. The graph shows how much revenue each model generated for the company over the last 5 years.

Complete the paragraph.

Compared to the other models, the amount of revenue generated by the model has remained the most constant. The amount of revenue generated by that model as a proportion of the total revenue generated by all 4 models has because the total revenue has .

solution

The graph shows that the amount of revenue generated by the Dahlia model has remained at about

0.2

billion dollars during years 1 through 5. The amount of revenue brought in by every other model has increased. So, compared to the other models, the amount of revenue generated by the Dahlia model has remained the most constant.

The total revenue generated by all 4 models has increased during years 1 through 5, from about

0.9

billion dollars in year 1 to about

2.1

billion dollars in year 5.

The revenue generated by the Dahlia model has remained relatively constant and the total revenue has increased. In year 1, the Dahlia model generated about

0.2

0.9

≈

22%

of the total revenue. In year 5, it only generated about

0.2

2.1

≈

10%

of the total revenue. So, as a proportion of the total revenue, the revenue generated by the Dahlia model has decreased.
