10.5 %

Skills needed: Financial Math Essentials

Step-by-step explanation:

1) First, before getting started, let's assume the price of the product is . This variable will be used a lot throughout the problem ().

2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by percent, the new price would be .

---> In this case, the price increased by percent.

This means that it would be:

New price is:

3) The shopkeeper is then offering a percent discount off of this marked price. When offering a percent discount price, the new price (with discount), expressed algebraically is:

---> the expression above simplifies to

In this case, ,

--->

This means that , with discount, has been raised .

10.5 % is the profit percent

(The profit percent being the final marked up price - purchased price)

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

yes because they have the same amount of green and blur marbles.
