6: john has a coupon for 20% off any item in a store. what would the final cost be for an item that originally cost $15 if he uses his coupon? (assume there are no taxes)

$12

Step-by-step explanation:

The coupon is 20% off any item in a store.

The cost of item originally is $15

Using the coupon that applies 20% off it will be;

80/100 *15 = $1280/100 will give you the cost of the item after 20% off is applied.This is like reducing the price by 20%

Final cost of item after using his coupon will be $12

For this case, we propose a rule of three taking into account that the original cost of the item is $ 15.

$ 15 ---------------> 100%

x --------------------> 20%

Where x represents the amount of money saved by the discount.

Thus, the discount coupon was equivalent to $ 3 for that item.

$15- $3 = $12

Thus, the item cost $ 12 using the coupon.

The item cost $ 12 using the coupon.
