Answer:
B, hope this helps!
Step-by-step explanation:
Functions can not have repeating X values.
1) Find the value of x and y.
2) Then use the Order of Operations to help you out with the computation.
ANSWER: x = 4 ( 8 + 160 )
STEP BY STEP:
Let's start by getting a variable to represent the number. Let's use x. ⇩
x=
Now we know that there is a sum of 8 and 160. Let's add them to each other ⇩
x= 8 + 160
Now we know that this will be multiplied. Let's put parentheses around the addition to symbolize this.
X= (8 + 160)
Finally multiply this by four, making your equation
x= 4 (8 + 160)
I don't know the options but from looking at the problem I'm assuming the answer is
x = 4 ( 8 + 160 )
80% of 20 is 80/100 x 20 = 16
So, kelly has used 16 stamps, and has 4 left
