Question

Which is the best buy, 6 shirts for $25.50 4 shirts or $18.00 5 shirts for $21?

Answer 1

The best buy is `5` shirts for `$21.00`.

Explanation:

`6` shirts for `$25.50` means that unit rate is `$25.50/6=$4.25`,

`4` shirts for `$18.00` means that unit rate is `$18.00/4=$4.50`

and `5` shirts for `$21.00` means that unit rate is `$21.00/5=$4.20`

As unit price is least in case of `5` shirts for `$21.00`, this is the best buy.
