Answer:
$40
Step-by-step explanation:
Let the original price of the item be x.
From the first statement, the price of the item was reduced 25% to $30. This means that new price of the item is now 75% (0.75) of the original price(x), and this new price is equal to $30. i.e
0.75x = 30
Now, let's solve for x.
0.75x = 30 [divide both sides by 0.75]
= ![\frac{30}{0.75}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B0.75%7D)
x = 40.
Therefore, the original price of the item was $40
You have a fifty-fifty chance, so you would expect it to land on heads five times and for it to land on tails five times. Hope this helps!
