In a class of 6060 students, 4040 are democrats, 1010 are business majors, and 33 of the business majors are democrats. if one student is randomly selected from the class, find the probability of choosing a democrat or a business major.

100(whole class is 100%) / 6060(number of students total) = any random student chance
0.0165
A) for democrats multiply chance of any random student with number of democrats
0.0165×4040=66.66666...
B) for business majors, multiply that chance with number of business​ majors
0.0165×1010=16.66666...
C) for both business major and democrat multiply chance with numbers of students who are both
0.0165×33=0.544...

$24

Step-by-step explanation:

So the total number of hours John has worked after 4 hours plus another 2 hours is h = 4 + 2 = 6 hours.

Given that John's wage is modeled by the equation w = 4h, then his total wage within 6 hours of working is is

w = 4h = 4 * 6 = $24
