Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable solut
castortr0y [4]
Each day, 30 cents are added onto the fee.

-3 days would mean -3 * 30 cents on the fee, which is -90 cents, or -0.90.
and -2.5 charges of 30 cents would be -75 cents!
...but you can't have negative days or fees, so A and B are out of the question.

4.5 charges of 30 cents IS $1.35...
...but the library charges by day, of course.

8 charges of 30 cents would be $2.40, and both of these are realistic possible numbers.

A Family purchased tickets to the movies in spent a total of $40.75. The family purchase five tickets there was a $.90 processi
muminat

Answer:

$7.25

Step-by-step explanation:

Total amount spent on the ticket   = $40.75

Number of ticket purchased  = 5

Processing fee per ticket  = $0.90

Unknown:

Cost of each ticket = ?

Solution:

To solve this problem, we need to find the processing fee for the 5 tickets purchase;

      Processing fee = number ticket x processing fee per ticket

      Processing fee  = 5 x 0.9  = $4.5

Now, the real cost a ticket = $40.75  - $4.5  = $36.25

So, cost per ticket is;

        Cost  = \frac{36.25}{5}   = $7.25

An Uber fare in Columbus is $3.50 for the first ½ mile and additional mileage charged at a rate of $0.30 for each additional 0.1
Verizon [17]

Answer:

\frac{11}{3} miles

Step-by-step explanation:

Let the total miles traveled be x.

Now, for the first 0.5 miles total charge is = $3.50

Then, the remaining distance to be traveled=(x-0.5) miles

For each additional 0.1 mile, the additional charge is $0.30

So, for (x-0.5) miles, the total additional charge will be=\frac{0.3}{0.1}(x-0.5) =3(x-0.5)

Then, including the $2 tip, the total fare will be=3.50+3(x-0.5)+2

Now, given that total fare is $15, so,

3.50+3(x-0.5)+2=15\\3.50+3x-1.5+2=15\\3x+4=15\\3x=11\\x=\frac{11}{3}miles
