1) Find the percentage difference between 12% and 100%.
100-12= 88%
1a) Put the percentage in its decimal form.
88%/100= 0.88
2) Divide 17.60 by 0.88
17.60/0.88= 20
Therefore, the original price of the lamp is $20.
Hope this helps!
When you multiply/divide by a negative number while solving the inequality, you reverse the symbol.
A.) 4(5 - y) ≥ 80 To solve this, isolate/get the variable "y" by itself in the inequality. Divide 4 on both sides

5 - y ≥ 20 Subtract 5 on both sides
5 - 5 - y ≥ 20 - 5
-y ≥ 15 Divide -1 on both sides to get "y" by itself
Because you are dividing by a negative number, you need to reverse the sign
y ≤ -15
B.) 2(y - 3) ≥ 8 Isolate "y", divide 2 on both sides
y - 3 ≥ 4 Add 3 on both sides to get "y" by itself
y ≥ 7
C.) 3y - 4 > 1 Add 4 on both sides
3y > 1 Divide 3 on both sides to get "y" by itself

D.)
Isolate "y", add 3/4 on both sides
6y > 1 Divide 6 on both sides to get "y" by itseld

Answer:i think you have to equal them to each other
Step-by-step explanation:
You multiply each by four to get the next number.
2*4=8
8*4=32
32*4=128
The next one in sequence would be 512. Since 128*4=512
