Answer:
Adult required in the case of “a” 28 and in the case of “b” the adult requirement is 19.
Step-by-step explanation:
(a) The percentage of adult that support the change is 20 percent.
Now calculate the number of adult required.
Given p = 0.20
Use the below condition:
Since 35 adults are already there so required adults are 63 -35 = 28
(b) The percentage of adult that support the change is 25 percent.
Now calculate the number of adult required.
Given p = 0.25
Use the below condition:
Since 35 adults are already there so required adults are 54 -35 = 19
.
A. -x=-22-38
-x=-60
Tú correcta respuesta es x=60
B. x+45
x=35-42
Tú correcta respuesta es x=-7
C. 18+x+-8=4
18+x-8=4
x+10=4
x=4-10
Tú correcta respuesta es x=-6
Thus the expression is 0.15x.
Given,
A reasonable tip for some is 15% of the subtotal.
We need to write an expression that would represent how much tip you should leave if x represented the subtotal.
<h3>How to write the percentage of a quantity?</h3>
Let the quantity be 100.
5% of 100 = 5/100 x 100 = 5
10% of 100 = 10/100 x 100 = 10
50% of 100 = 50/100 x 100 = 50
We have,
Subtotal = x
Tip = 15%
Write the expression for 15% of x
15% of x
= 15/100 x (x)
= 0.15x
Thus the expression is 0.15x.
