Abag of sweet and sour jelly beans has 22 jelly beans. if 8 of the jelly beans are sweet and 6 of the jelly beans are red, and 10 jelly beans are neither sweet or red, how many sweet red jelly beans are in the bag

When you subtract 10 from 22, the difference would be 12. This means that there are 12 beans that are either sweet or red. Another statement was that, there are 8 sweet jelly beans and 6 red jelly beans. However, if you total everything, 8+6+10, the sum would be 24. That would be more than the total number of beans in the bag which is 22. So, this means that 2 of those beans are sweet jelly beans and they are already included in the count for either the 8 or 6 sweet and red jelly beans, respectively.

The answer would be 2 sweet red jelly beans.

Product A has a greater percentage change in price.

Step-by-step explanation:

Part A:

The price f product A, f (x) after x years is given by: 

 

After x = 0 years, the price of product A is:

After x = 1 years, the price of product A is:

After 1 year, the price of product A is 3% times more than the original price.

This means that after one year, the new price is 103% of the original price, which means the price product A is increasing by 3%.

Again after x = 2 years, the price of product A is:

This implies that after 2 years, the price of product A is 103% of the price after year 1.

This implies that the price of product A is 3% more than the previous year.

Thus, the price of product A is increasing each year by 3%.

Part B:

The data for Product B is as follows:

Time (t)          Price [f (t)]

   1                   10,100

   2                   10,201

   3                 10,303.01

   4                 10,406.04

Product B is clearly increasing in price.

Consider the changes in price of Product B in the following intervals of years:

Year 1 - Year 2:

Price in year 1 = $10,100

Price in Year 2 = $10,201

Compute the increase percentage as follows:

Year 2 - Year 3:

Price in Year 2 = $10,201

Price in year 3 = $10,303.01

Compute the increase percentage as follows:

Year 3 - Year 4

Price in year 3 = $10,303.01

Price in Year 4 = $10,406.04

Compute the increase percentage as follows:

It is quite clear that the price of product B increases by 1% each year.

Thus, Product A has a greater percentage change in price.
