Answer:
x = 1
Step-by-step explanation:
Given
5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )
5(2x - 8) = - 30 ( divide both sides by 5 )
2x - 8 = - 6 ( add 8 to both sides )
2x = 2 ( divide both sides by 2 )
x = 1
The decrease was 3. (from 30 down to 27)
Always calculate the decrease as a percent of the ORIGINAL number.
3/30 = 0.1
To change a decimal to a percent, move the point 2 places that way ==> .
0.1 = 10% .
When you go from 30 to 27, that's a decrease of 10% .
