Question

The Holt family is purchasing 4 cell phones. Store A sells 3 cell phones that cost $165 each, which includes a fourth phone for free. Store B sells the same cell phone for $135 each. Which store has the better deal for purchasing 4 cell phones? Explain.

Answer 1

Answer:Store A

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
`(165* 3)/(4)=\$ 123.75`

Store B sells each cell phone at
`\$ 135` each

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

`\Rightarrow 165*3 <135*4\\\Rightarrow \$495<\$540`
