A lamp sold for $17.60, which represented a 12% discount. What was the original price of the lamp​
guajiro [1.7K]

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!

You need to reverse the symbol to solve which inequality?
Marina86 [1]

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

\frac{4(5-y)}{4} \geq \frac{80}{4}

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

\frac{-y}{-1} \geq \frac{15}{-1}       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

y>\frac{1}{3}

D.) -\frac{3}{4} +6y > \frac{1}{4}       Isolate "y", add 3/4 on both sides

6y > 1     Divide 6 on both sides to get "y" by itseld

y>\frac{1}{6}

2, 8, 32, 128<br> what is the sequence?
vovikov84 [41]
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
