Answer:
bags of popcorn = 10%
sodas = 15.78%
overall increase was 12.5%
Step-by-step explanation:
We must calculate the unit price of each product, before and after.
Before:
bags of popcorn = 7.50 / 3 = 2.5
sodas = 3.80 / 2 = 1.9
Then:
bags of popcorn = 8.25 / 3 = 2.75
sodas = 4.40 / 2 = 2.2
Now, we calculate for each:
bags of popcorn = 2.75 / 2.5 = 1.1
which means that the increase was 10%
sodas = 2.2 / 1.9 = 1.1578
Which means that the increase was 15.78%
If we calculate the percentage of total increase it would be:
(2.75 + 2.2) / (2.5 + 1.9) = 1,125
Therefore the overall increase was 12.5%

Answer:
$0.22
Step-by-step explanation:
Ellen has a coupon of 1.55 off a loaf of bread
The regular price of the bread is 4.63, the loaf is cut into 14 slices
Therefore if she uses her coupon the price per slice can be calculated as follows
= 4.63-1.55
= 3.08
3.08/14
= 0.22
Hence the price is $0.22
Answer: The volume of the grapefruit is approximately 8 times as great as the volume of the lime.
Step-by-step explanation:
You need to use the formula for calculate the volume of a sphere. This is:
Where "r" is the radius.
<u>Volume of the grapefruit</u>
You know that its diameter is 16 centimeters.
Since the radius is half the diameter, you get that its volume is:
<u> Volume of the lime</u>
According to the information given in the exercise, the diameter of the lime is 8 centimeters.
As it was explained above, the radius is half the diameter. Knowing that, you get that volume of the lime is the shown below:
In order to find approximately how many times as great is the volume of theat grapefruit as the volume of that lime, you need to divide the volumes calculated above. Then:
A line can be defined simply with the use of two points - one for each end. In a similar way, a plane can be defined using three points. However, if each of the points are collinear - they will instead define a line. Therefore, three points defining a plane can be produced only by three non-collinear points. The plane will pass through these three points and in principle is infinite in extent.
