Answer:
Therefore Marcus is incorrect.
Step-by-step explanation:
Total ticket that Marcus bought= 100%.
Marcus used 50% of ticket on rides.
and he used of the tickets on the video games.
The percentage form of any number x is
The percentage form of is
=25%
Therefore rest tickets are
=Total ticket-( ticket used in rides + ticket used in video games)
=100% - (50%+25%)
=100% - 75%
=25%
Therefore he used 25% of tickets in batting cage.
But he said that Marcus said that he used 24% of ticket in batting cage.
Therefore Marcus is incorrect.
The linear equation in slope intercept form for population of Jose's town is y = 320x + 2400.
<u>Solution:</u>
Given, the population of Jose's town in 1995 was 2400 and the population in 2000 was 4000,
Let x represent the number of years since 1995.
We have to write a linear equation, in slope- intercept form, that represents this data.
Now, let the change in population per year be p.
Then, population in a year = population change per year number of years + population in 1995.
⇒population in a year = p x + population in 1995
⇒ population in a year = p x + 2400
Here we have an case that, population in 2000 is 4000
Then, number of years since 1995 = 5
So, 4000 = p 5 + 2400 ⇒ 5p = 4000 – 2400 ⇒ 5p = 1600 ⇒ p = 320
Then, our equation will be population in a year = 320x + 2400
Considering the population in a year as y ⇒ y = 320x + 2400.
Hence, the linear equation in slope intercept form is y = 320x + 2400.
