Answer:

The maximum earning is $122

Step-by-step explanation:

The computation of the Daniel maximum earnings is as follows;

Since there is total of 16 hours

so 10 hours would be for parking cars and the remainig hours i.e.

= 16 hours - 10 hours

= 6 hours

This above hours for working at store

So,

= 10 hours × $8 + 6 hours × $7

= $80 + $42

= $122

Hence, the maximum earning is $122

dimaraw [331]

Answer:

a). 18

b). 26%

c). 39

Step-by-step explanation:

Given question is incomplete; here is the complete question attached.

a). In this part we have to calculate the number of the people surveyed who make less than 5 calls.

From the given table,

Number of people surveyed who make less than 5 calls Or 1 - 4 calls = 18

b). Total number of people surveyed = 18 + 11 + 5 + 3 + 2 = 39

Number of people surveyed, make at least 9 calls = 5 + 3 + 2 = 10

Percentage of these people = \frac{\text{People who make calls more than 9 calls per day}}{\text{Total number of people surveyed}}\times 100

= \frac{10}{39}\times 100

= 25.64%

≈ 26%

c). Total number of people surveyed = 18 + 11 + 5 + 3 + 2 = 39
