Sally found the deal of the century when buying a TV. • The store advertised the TV for 1/3 off. • At the register she handed the cashier a coupon for an additional 1/4 off. If the TV originally cost $320 how much did she pay for it?

$160

Step-by-step explanation:

These discounts would be added one after the other. Therefore, we would first apply the first discount of 1/3 to the original price. Since it is a discount it means that from the original price we would pay 2/3. We do this by multiplying this fraction by the original price like so...

$320 * (2/3) = $213.33

Now we add the second discount of 1/4. Again, since it is a discount it means that we would be paying 3/4 of the current price.

$213.33 * 3/4 = $160

Finally, we can see that Sally would have ended up paying $160 for the TV.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
