Grace walked 32 miles last month. So far this month she has walked 5 eighths as far as last month. How far has grace walked this month

Answer: Club A

EXPLANATION

Given,

Club A charges $12 for membership and $2 for each rented video.

The deal in Club A can be represented by the function, f(x) = 12 + 2x

Club B charges $4 for membership fee and charges $4 for each rented video.

The deal in Club B can be represented by the function, f(x) = 4 + 4x

To determine which video rental club is the better deal

First, we find the number of videos where the amount spent will be the same

That is, when 4 + 4x = 12 + 2x

Subtract 4 from both sides of the equation

4 + 4x – 4 = 12 + 2x – 4

4x = 8 + 2x

Subtract 2x from both sides of the equation

4x – 2x = 8 + 2x – 2x

2x = 8

Divide both sides by 2

2x/2 = 8/2

x = 4

Since the deals for club B and club B will be of equal expense by the time a total of 4 videos have been rented, the better deal is the one that is cheaper when more than 4 videos have been rented.

Take a random value of x that is greater than 4, say 6

For the deal in Club A, f(x) = 12 + 2x

= 12 + 2(6)

= 12 + 12

= $24

For the deal in Club A, f(x) = 4 + 4x

= 4 + 4(6)

= 4 + 24

= $28

Since the deal in Club A is cheaper on the long run (i.e for 5 videos and above), it is a better deal than that of Club B

The friend will get 12 issues for $15.

What is a Ratio?

A ratio indicates the number of times one number contains another.

Given that, the friend pays $1.50 per issue:

$1.5 = 1 issues

$1 = 1/1.5 issues

$15 = (1/1.5) × 15 issues

$15 = 10

Since the friend gets the first two issues free, he will get 10 + 2 =12 issues.

Hence, the friend will get 12 issues for $15.

Answer:

PLZ MARK ME BRAINLIEST.  

Step-by-step explanation:

Number Of Students who go to School by Walk  = 27

Number Of Students who go to School by Bus  = 45

Ratio of Student who go to School by Walk :  Bus  = 27 : 45

=> Ratio of Student who go to School by Walk :  Bus  = 3 : 5

Hence Ratio of Student who walk to students who ride the Bus  is  3 : 5 is correct  -  True Statement

Number Of Students who go to School by Bike  = 21

Number Of Students who go to School by Walk  = 27

Ratio Bike : Walk = 21 : 27

=> Bike : Walk = 7 : 9

Hence for Every 7 Students who Bike there are 9 students who walk

=> For Every 7 Students who Bike there are 8 students who walk is not Correct

Answer:

Adrian must work at least 8 hours in a day to make more than $260

Explanation:

Assume that Adrian needs to work x hours in one day to make at least $260

We know that she makes $42 per hour

This means that:

If she worked x hours in a day, then she'll earn $42x

We are also given that she spends $75 daily on dry clean

This means that:

Amount she makes in a day = amount she earns - $75

Amount she makes in a day = 42x - 75

Now, she wants to make at least $260

This means that:

42x - 75 ≥ 260

42x > 260 + 75

42x > 335

x > 7.9

Therefore:

Adrian must work at least 8 hours in a day to make more than $260

Hope this helps :)
