You need do like 25$--------100% of real price
                         x$---------70%
25x70=100<u>x</u>
1,750=100<u>x</u>
    <u> x</u>=1750<u />divided by 100=17.5$

Answer:
Independent events
Step-by-step explanation:
Given that:
Ramiro draws a marble from a jar without replacement and then flips a coin
Let  be the event that Ramiro draws a marble without replacement and;
 be the event that Ramiro draws a marble without replacement and;
Let  be the event of flipping a coin.
 be the event of flipping a coin.
Let's have an analogy so that we can better understand the concept of independent and dependent events.
Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.
The event  does not in any way affect the event
  does not in any way affect the event  of a head or a tail showing up in  a flip of a coin.
  of a head or a tail showing up in  a flip of a coin. 
Therefore, we say that  and
  and  are independent events.
   are independent events.
Suppose the event   affects or influence the event
  affects or influence the event  , then we can say they are dependent events.
  , then we can say they are dependent events.
