Negative and a positive makes a negative.
So, -25 + 25 = 0
Answer:
............................
4/5 (2x + 5) − 4 =1
4/5(2x +5) = 1 +4
4/5 (2x +5) = 5
2x + 5 = 5 / (4/5)
2x + 5 = 5 (5/4)
2x + 5 = 25/4
2x = 25/4 - 5
2x = 25/4 - 20/4
2x = 5/4
x = (5/4) / 2
x = (5/4) (1/2)
x = 5/8
x = 0.625
$570
Step-by-step explanation:
If she marks up the sofa for 90%, she will change the price to 760$
Now, 25% of 760$ is 190$. So, we subtract 190 from 760 and get 570$
