Multiply Decimals

Question

The postage cost of a parcel is $2.15 per gram and $0.85 for each additional gram. Mike wanted to post a package weighing 72 grams. How much did he pay for the postage?

Answer 1

I'd like to confirm the wording of the question. The question as written states:

"The postage cost of a parcel is $2.15 per gram and $0.85 for each additional gram."

There seems to be some information missing. Is it supposed to read "$2.15 per parcel"? Or is there a weight limit; i.e., "$2.15 per gram and $0.85 for each additional gram over 60 grams"?

Thanks for confirming!
