Felisha goes to Academy Sports and Outdoors and purchases two pair of socks at $20 each. The socks are on sale for “buy 1 get 1 half off!” The store is having a deal of buy $50 worth and get 20% off your total purchase, so Felisha buys a $20 hoodie. Assuming there is no taxes, how much did Felisha spend, save, and what was the total discount percent?

Answer:


Step-by-step explanation:

The trick here is when do the discounts take place? The "buy 1 get 1 half off" must take place before the total is computed to get the 20% off.

So she spends

First pair of socks:       20

Second Pair: 20 - 10 = 10

Hoodie:                        20

Total:                            50

Now she gets another 20% off which means that she still pays 80% of her purchases. (80 / 100) * 50 = 4000/100 = 40 dollars which is ultimately what she spent.

She saved a total of 10 + 10 = 20 dollars.

The % discount is (20 /  60  (which is what she should have paid) ) * 100

The % discount = 1/3 * 100 = 33.3 %
