Answer:
$90
Step-by-step explanation:
First the given is the listed price of DVD which is 120 dollars.
Now we need to find out what the price will be after discount of 25%
To do this we will have to convert the percentage to decimal by moving decimal 2 place left and removing percentage sign which will become 0.25.
Then we multiply by the listed price which is 120
so 120*0.25=30
so we subtract 30 by original price cause that is the discount off we are receiving
120-30=90
so 90 will be the sale price after 25% discount.
Answer:
A set of natural numbers less than 10
is
<u>N{1,2,3,4,5,6,7,8,9}</u>
The answer is 6
Explanation:
Set up a ratio
The percentage of candy bars left is
100
−
70
=
30
Let 30% be the partial percentage.
Let 100% be the total percentage.
Let x be the partial number of candy bars.
Let 20 be the total number of candy bars.
30
100
=
x
20
Multiply both sides by 20
30
×
20
100
=
x
×
20
20
This leaves
600
100
=
x
Dividing by 100 gives
6
=
x
.
There are 6 candy bars left
Upper + Lower surface area= 2(12*12-36)=216cm^2
Side surface area=6*4*4=96+12*4*2=192
Total surface area= 216+192=408cm^2
