Question

Store I offers a pair of shoes Karen wants for 25% off their regular price of $12.00. Store J sells the same pair of shoes for $10, before a $2.00 mail-in rebate. Where should Karen purchase her shoes? Explain your reasoning. (Be sure to consider the cost of postage, as well as the time and effort required to mail in the rebate request in your response.)

Store I 12 x 0.25=$3 12-3=9

Store j

Answer 1

In store I :-

The discount:-

`\\ \sf\longmapsto 12* 25\%`

`\\ \sf\longmapsto 12* (25)/(100)`

`\\ \sf\longmapsto \$ 3`

Cost of shoe

`\\ \sf\longmapsto 12-3`

`\\ \sf\longmapsto \$ 9`

In store J:-

The Cost of shoe :-

`\\ \sf\longmapsto 10-2`

`\\ \sf\longmapsto \$ 8`

Karen should purchase shoes from store J

Answer 2

This is already solved half-way.

Store I, 25% off:

• $12 - 25% =
• $12 * (1 - 0.25) =
• $12 * 075 =
• $9

Store J, $2 off:

• $10 - $2 =
• $8

A pair of shoes cost $9 in store I and $8 in store J.

Karen should purchase her shoes from the store J as it costs $1 less.
