The admission to a local carnival is $6.50 per person and $2.50 for each ride. jenna wants to know much it will cost her to ride a certain number of rides at the carnival. which equation can she use to create a table with this information (where p is the number of persons, r is the number of rides, and t is the total cost of admission and rides)?
6.50p + 2.50 = t
6.50 + 2.50r = t
6.50r + 2.50 = t
6.50 + 2.50p = t

Step-by-step explanation:

Given : The admission to a local carnival is $6.50 per person and $2.50 for each ride.

To Find: Which equation can she use to create a table with this information (where p is the number of persons, r is the number of rides, and t is the total cost of admission and rides)?

Solution:

We are given that Jenna wants to know much it will cost her to ride a certain number of rides at the carnival.

Since no. of person is 1

So, Admission cost for Jenna is $6.50

Now let us suppose she wants to have r number of rides.

Cost of 1 ride = $2.50

Cost of r ride = $2.50r

So, total cost of Jenna = 6.50+2.50r

Since we are given that t denotes the total cost

So,

Hence she use an equation to create a table with this information.

So, option B is correct.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
