Apackage of 12 cakes costs $6.80. a package of 30 cakes of the same type costs $15.16. which package is the best buy? give the unit cost of the best buy to the nearest cent.

All you need to do is divide the number of cakes by the price. 

6.80/12= .56 repeating 

15.16/30= .51

The better buy is the second one. The unit costs are one for .56 and one for .51. 

I hope this helped you!

Brainliest answer is appreciated!

Idon’t know how to do that
