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.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
