Answer:
255 gallons
Step-by-step explanation:
The level at Jackson & Jacinto Auto Repair should order more oil is the re-order point.
To calculate the re-order point, we require for Jackson and Jacinto.
Average daily usage
Delivery lead time ... which is three days
The average daily usage for oil is 510 gallons divided by six working days
= 510/6
= 85 gallons
Formula for getting the re-order point
= (average daily usage x delivery time)
= (85 x 3)
=255 gallons
They should re-order when they have a balance of 255 gallons
