Respuesta :

Answer:

b = 5

Step-by-step explanation:

Given the next functions:

J(b) = 14b + 7

W(b) = 7b + 42

where b represents the number of hamburgers cooked and J(b) and W(b) represent the amount of time each cook takes in minutes. When J(b) equals W(b) their cooking time will be equivalent,  then:

14b + 7 = 7b + 42

14b - 7b = 42 - 7

7b = 35

b = 35/7

b = 5
