Answer:
[tex]32[/tex]
Step-by-step explanation:
Given
Number of service bays [tex]= 2[/tex]
Time taken by each bay to finish one oil change [tex]= 30 minutes[/tex]
Working capacity [tex]= 8[/tex] hours per day
Thus, in [tex]8[/tex] hours the total number of times one bay has changed the oil is equal to
[tex]\frac{8 * 2 * 30}{30} \\= 16[/tex]
If one service bay's capacity is equal to [tex]16[/tex], capacity of two service bays is equal to
[tex]16 * 2 \\= 32[/tex]
Thus, the design capacity is [tex]32[/tex]
