Raina earns 47 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells. Let A be the amount (in dollars) that Raina earns in a week if she sells B books. Write an equation relating A to B. Then use this equation to find the amount of money Raina earns if she sells 12 books.

$564

Step-by-step explanation:

Let A be the amount (in dollars) that Raina earns in a week if she sells B books.

Given: Raina earns 47 dollars each week working part-time at a bookstore.

Total earning = (Earning per book)x (Number of books)

i.e. A = 47B

Put B = 12

A = 47(12) =564

Hence, the amount of money Raina earns if she sells 12 books is $564 .

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 .
