Respuesta :

1st gift shop:

120/4 = 30 cents each

180/6 = 30 cents each

390/13 = 30 cents each

 

2nd gift shop:

204/7 = 29.14 cents each

192/8 = 24 cents each

270 /9 = 30 cents each

360/10 = 36 cents each


 so if both gift shops have a fixed price then the 9 post cards would be the answer since it matches 30 each like the 1st gift store
