In general accounting practice, transportation (shipping) costs are allocated to specific items in a multi-item order by the relative cost of each item. Example: A 2-item order totals $100 (say, $60 for one item and $40 for the other), and the shipping cost is $10. The shipping cost for the $60 item is $60/$100*$10 = $6, and the shipping cost for the $40 item is $4.
£2 = 200 pence 200 pence = 10 items 20 pence = 1 item
54 cents.
Let the lower value item cost $n. Then the higher value item costs $(n + 10).n + (n + 10) = 100 : 2n + 10 = 100 : 2n = 90 : n = 45 therefore n + 10 = 55.The two items cost $45 and $55.
1 minus 10% = 90% = 0.90.9 x 4.33 = $3.90 (rounded)
