Russia bought 9 books for $3 each sold them making a profit of $18 for what price did she sell each book?​

$45

Step-by-step explanation:

Profit= $18

Sold each at = $3

So, total CP (Cost Price)= 9*3 = $ 27

Also Profit = SP - CP

Therefore, SP = Profit + CP

= 18 + 27 = $45

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
