i don't understand this question.it is straight out of my math book:

The following prices were posted at the local store.
Bananas:.39c a pound

Notebook Paper: 1.02c

What is wrong with these signs?

The .39c a pound sign is a . for the dollars as well as a c for the cents. $.39 would be correct OR 39 c would be correct.

The second sign does the same. It would be correct to list it as 102 c OR $1.02

thank you very much!!

How do i tranfer formulas?

To understand what might be wrong with the signs, let's analyze the given prices:

1. Bananas: .39c a pound
This price seems correct, as it states the cost per pound of bananas. However, it's worth noting that the symbol used is "c" which typically stands for "cents," not "pound." A more appropriate symbol would be "$" for dollars.

2. Notebook Paper: 1.02c
This price suggests that notebook paper costs 1.02 cents. However, it is unusual to express prices in fractions of a cent, particularly when dealing with everyday items. Instead, prices are commonly expressed in whole cents or dollars. Therefore, the correct format would be $1.02 or 102 cents.

In summary, the errors in the signs are potentially the use of "c" instead of "$" for bananas and the unusual representation of notebook paper price as 1.02 cents instead of $1.02.
