Divide the amount saved by the original price then multiply by 100 to get the percent:
6/40 = 0.15
0.15 x 100 = 15%
Easy peasy lemon squeesy :D (-.-)! more blueberries! omgydnkhtdt(Oh my god you do not know how to do this
Solution:
1) Add 80 to both sides
-np<60+80
2) Simplify 60+80 to 140
-np<140
3) Divide both sides by p
-n<\frac{140}{p}
4) Multiply both sides by -1
n>-\frac{140}{p}
Done!
Here's the answer right here
