CD sales at corner music increased 145% last year. which number is equivalent to 145%?
A. 14,500
B. 145
C. 1.45
D. O.O145
i think C but im not sure
100% of something = the whole thing or 1
50% of something = .5 or 1/2 of the whole thing = .5
145% of something = 1.45
yes, C is the right choice.
To find the number that is equivalent to a certain percentage increase, you can use the formula:
New Value = Original Value + (Original Value * Percentage Increase)
In this case, the original value is the CD sales at corner music, and the percentage increase is 145%.
Let's assume the original CD sales at corner music were X. Then, the new CD sales would be:
New CD sales = X + (X * 145%)
To determine which number is equivalent to 145%, let's plug in the values from the options provided:
A. 14,500:
New CD sales = X + (X * 14,500%) = X + (X * 145)
This option represents a direct increase of 14,500, which is not equal to a percentage increase of 145%.
B. 145:
New CD sales = X + (X * 145%) = X + (X * 145/100) = X + (1.45X) = 2.45X
This option represents an increase of 145 units, which is not equal to a percentage increase of 145%.
C. 1.45:
New CD sales = X + (X * 145%) = X + (X * 1.45)
This option represents an increase of 1.45 units, which is equal to a percentage increase of 145%.
D. 0.0145:
New CD sales = X + (X * 145%) = X + (X * 0.0145)
This option represents an increase of 0.0145 units, which is not equal to a percentage increase of 145%.
Therefore, the correct answer is C. 1.45.
