ivanzaharov [21]

Answer:

The\ bank\ from\ yuris\ house\ is \frac{1}{3}\ miles.

Step-by-step explanation:

The\ store\ is\ \frac{5}{6}\ mile\ from\ yuri's\ house.

The\ bank\ from\ yuris\ house = \frac{1}{3}\ miles

Yo save a step you can just find the percent of 25 that you have to pay if 20% was taken off the regular price. What percent of
Anton [14]

Answer:

I have to pay 20% of the regular price.

Step-by-step explanation:

Let the regular price of the item is $x.

Now, I have to pay 25%, if the regular price of the item was 20% taken off the regular price.

So, the price of the item after the 20% price is taken off the regular price is x(1 - \frac{20}{100}) = 0.8x.

So, I have to pay 25% of that price, i.e. 0.8x \times \frac{25}{100} = 0.2x

Now, if I have to pay y% of the regular price, then

x \times \frac{y}{100} = 0.2x (Given)

⇒ y = 20%

Therefore, I have to pay 20% of the regular price. (Answer)
