Suppose you want to buy 100 pens. You can buy 100 pens at a 10% discount at one store where the price is $6.99 per pen. And you can also buy 100 pens at a 15% discount at another store where the price is $7.48 per pen. Required:
a. What is the price per pen at the first store?
b. What is the price per pen at the second store?
c. What is the total price difference for 100 pens?

a. $629.10

b. $635.80

c. $6.70

Step-by-step explanation:

The first thing we need to do is turn these percentages into decimal values by dividing them by 100, this would make 10% into 0.10 and 15% into 0.15. Now we can make the following equations to calculate the total by multiplying the 100 pens by the individual pricer per pen, and then multiplying that product by the 1 minus the discount percentage.

A)    (100 * 6.99) * (1 - 0.10) = x

          699 * 0.90 = x

              $629.10 = x

B)    (100 * 7.48) * (1 - 0.15) = x

          748 * 0.85 = x

              $635.80 = x

C)   635.80 - 629.10 = $6.70

The difference is $6.70 more for the 100 pens in the second store.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
