Question

To ship a package, a freight carrier charges $0.75 for the first pound and $0.25 for every pound (or part of a pound) over the first pound. A package weighs 3,456 grams. How many pounds does the package weigh? How much will it cost to ship the package?

Answer 1

Answers: Weight - 7.62 pounds, Cost - $2.50

When we convert 3,456 grams into pounds, we get 7.62 pounds (rounded to the nearest hundredth). We can subtract the first pound off since we know that will cost $0.75 (7.62 - 1 = 6.62 pounds). Now we must round 6.62 up to 7 pounds and multiply that by the price for every pound or part of a pound (7 x 0.25 = $1.75). Now you combine both the cost of the initial pound and the cost of every pound or part of a pound over the first to get your final cost. ($0.75 + $1.75 = $2.50)
