The cost of a cell phone was $200. Then it was discounted by 10%. What is the new cost of the cell phone? Explain what you did to solve the problem

Answer with explanation:

You first have to find 10% of $200. To do this, you have to multiply the decimal form of 10% with 200.

So,

10% of 200

0.1 of 200

0.1 × 200 = 20

Now since the 10% acts as a discount, you subtract the 10% of 200 from $200.

$200 - 20 = $180

So the new price of the phone is $180.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
