Problema Solution
You order from a catalog the following office supplies: 10 boxes of paper, each box is 6 pounds and 36 boxes of pens, each box weighs 12 ounces. Shipping charges are $12.00 for first 20 pounds, $10.00 for the next 30 pounds, $0.50 per pound for next 50 pounds. What will the shipping charges be?
Answer provided by our tutors
1 pounds = 16 ounces
1 ounce = 1/16 pounds
12 ounces = 12/16 pounds = 3/4 pounds
The total weight of the office supplies is:
10*6 + 36*(3/4) = 60 + 27 = 87 pounds
87 = 20 + 30 + 37
The shipping charges for 87 pounds are:
12 + 10 + 0.50*37 = $40.50
The sipping charges will be $40.50.
