6 0

Answer:

$150

Step-by-step explanation:

You can do this by  forming an equation.

30% = 0.30.   Let the original price be x dollars. Then:-

x - 0.30x = 105

0.70x = 105

x = 105/0.70

x = $150

What is the percent of change of 24 songs to 78 songs
Novosadov [1.4K]
Subtract 24 to 78. Divide the answer by 24. Multiply it by 100. So the final answer is 225%.
We have a starting value of 24. In order to reach 78, we need to multiply a number to 24 and add it to 24.
Making the equation 24 + 24P = 78.
Transpose 24 to the other side, you’ll get 24P = 78--24.
24P=54.
Divide both sides by 24, you’ll get P = 2.25
Multiply 2.25 by 100 to get the percentage.
So, you’ll get the final answer 225%
