Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Dani brings two and half dozen cupcakes for her 2nd-grade class. There are 27 students (including Dani), 1 teacher, and 1 teacher’s aid. If 3 students called in sick that day, how many cupcakes are left after Dani gives one to everyone in the class?


### Response:
 Dani apporte 2 douzaines et demie de cupcakes, soit 2,5 x 12 = <<2.5*12=30>>30 cupcakes.
Elle a besoin de ce nombre de cupcakes pour nourrir tout le monde en classe, soit 27 + 2 = <<27+2=29>>29.
Trois élèves sont absents, il y a donc 29 - 3 = 26 personnes en classe aujourd'hui.
Il reste ce nombre de cupcakes après que tout le monde en ait reçu un : 30 - 26 = <<30-26=4>>4 cupcakes.
