Let, the amount she earned = x
Then, x * 40% = 50
x * 0.40 = 50
x = 50 / 0.40
x = 125

In short, Your Answer would be Option C

Hope this helps!

The pound has three kinds of dogs: pit bull, chihuahuas and mutts. All but 23 of the dogs are pit bull, all but 17 are chihuahua
Georgia [21]

Answer:

There are 68 dogs in the pound.

Step-by-step explanation:

Number of mutts dogs in a pound = M = 28

Total number of dogs in a pound = T

T = P+C+M=23+17+28=68

Elina [12.6K]

Answer:

b. 9.2 minutes

Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}

number of calls (x)           waiting time f(x) in minutes         f(x) *(x)

0                                                     0                                         0            

2                                                     3                                         6

4                                                     10                                       40

6                                                     15                                       90  

8                                                     10                                       80

10                                                     6                                       60  

\sum x = 30                                                                          \sum f(x) *x = 276

Therefore:

\sum (f(X)) = \dfrac{276}{30}

\sum (f(X)) = 9.2
