Ok so to solve for percent off
percent off means discount


so therefor we need to find how much was discounted
30-20.10=9.90

so we see that 9.90 was discounted
to find the percent we do
discount/total=percent discount
9.90/30=0.33

percent means parts out of 100
0.33/1 times 100/100=33/100=33%

answer is 33% discout

What directed number is suggested by the statement "I gained 3 pounds "?​
sammy [17]

Answer:

The directed number suggested is +3.

Step-by-step explanation:

A directed number is one that has either a positive or negative sign, so that it could be easily located on the number line. Thus, the sign shows the direction of the number. Examples are: -2, -1, +5, +6 etc.

From the given question, let the initial weight be represented by W, then:

I gained 3 pounds implies at that; 3 pounds was added to my initial weight. Thus, my present weight is my initial weight + 3 pounds.

i.e I gained 3 pounds ⇒ W + 3

So that the directed number suggested by the statement is +3.
