Answer:
B
Step-by-step explanation:
Use distributive property:
5(2x - 3) = 5x - 10
10x - 15 = 5x - 10
Isolate the variable:
10x = 5x - 10 + 15
10x = 5x + 5
10x - 5x = 5
5x = 5
x = 1
The answer is 25%
(1)
If 64 is 100%, 48 is how much percent:
64 : 100% = 48 : x
x = 100% * 48 : 64
x = 75
(2)
Percent of decrease is:
100% - x = 100% - 75% = 25%
The answer is D
A=54
B=54
C=54
D=48
