Question

From 1990 to 2000, the number of visits by the people to Bryce Canyon National Park increased by about 23.9 thousand visits per year. In 2000, there were about 1102.4 thousand visits to the park.

Answer 1

Write an equation that gives the number of visits (in thousands) as a function of the number of years since 1990

Explanation:

Answer 2

If from 1990 to 2000, the number of visits by the people to Bryce Canyon National Park increased by about 23.9 thousand visits per year. An equation that gives the number of visits as a function of the number of years since 1990 is: y(x)=1102.4+23.9x.

What is the equation?

x = number of years since 1990.

Total increase in the number of visits during this period is:

23.9×10=239 thousand visits

So, the equation for the number of visits as a function of the number of years since 1990 can be written as:

y(x)=baseline visits + rate of increase × x

y(x)=1102.4+23.9x

Hence, the equation is :

02.4+23.9x

where:

y(x)=number of visits in thousands

Therefore an equation that gives the number of visits as a function of the number of years since 1990 is: y(x)=1102.4+23.9x.
