Answer:
a. 2560 checkout
b. 3072 checkout
c. Old system = 3.85 checkout/$
New system = 5.56 checkout/$
Explanation:
Given:
Checkout lanes = 4
a.
How many checkouts did the old system provide in a shift?
Given
Lanes = 2
Time in use = 16 hours --- Convert to seconds
Time = 16 * 3600 = 57600 seconds
Checkout = 1 per 45 seconds
Number of check outs is calculated as:
2 lanes * 57600 seconds * 1 checkout / 45 seconds
Number of checkout = 2560 checkouts
b.
How many checkouts does the new system provide?
Lanes = 4
TimeTime in use = 16 hours --- Convert to minutes
Time = 16 * 60 = 960 minutes
Number of check outs is calculated as:
4 lanes * 960 minutes * 1 checkout / 1.25 minutes
Number of checkout = 3072 checkouts
c.
Given
Electricity costs for both setups are $0.06 per checkout
Bagging (material) costs are $0.12 per checkout with the old system
Bagging (material) costs are $0.20 per checkout with the old system
Cost for the old system is calculated by:
$0.06 * 2560 + $0.12 * 2560
= $153.6 + $307.2
= $460.3
Multifactor = 2560 checkout/$460.3
Multifactor = 5.56 checkout/$
Cost for the new system is calculated by:
0.06 * $3072 + 0.20 * $3072
= $184.32 + $614.4
= $798.72
Multifactor = 3072 checkout/$798.72
Multifactor = 3.85 checkout/$
