5. A six pack of dinner rolls costs $2.22. A sixteen pack of the same rolls
are $6.24 Which pack is the better buy?

Respuesta :

The sixteen pack because $6.24 divided by 16 is 0.39 per dinner roll
The 16 pack because the unit rate of the 16 pack is 0.39 which is cheaper than the six packs unit rate. :)
