5) = 14b7

b) = 75+ 42

where brepresents the number of hamburgers cooked and b) and Wb) represent the amount of time each cook takes in minutes. At what

value of b will their cooking time be equivalent?

A

6=5

B. 0-19

C 66

6=12

Answer 1

b = 5

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
