Respuesta :

Answer:Store A

Step-by-step explanation:

Given

Store A sells 3 cells phones that cost $165 each and offer 4 th one free

i.e. Effective cost of each cell phone is  [tex]\frac{165\times 3}{4}=\$ 123.75[/tex]

Store B sells each cell phone at [tex]\$ 135[/tex] each

clearly, store A provides a better deal than B because the cost of 4 cell phones is less for Store A i.e.

[tex]\Rightarrow 165\times3 <135\times4\\\Rightarrow \$495<\$540[/tex]
