d. $200.00

Ryan's  revenue last month if he sold 16 new books and 25 old books

 is  $337.50.

Step-by-step explanation:

The number of old books sold by Ryan = 25

The cost of each old book = $5.50

⇒ Total amount earned by selling 25 old  books = 25 x $5.50

                                                                                  =  $137.5

The number of new books sold by Ryan = 16

The cost of each new book = $12.50

⇒ Total amount earned by selling 16 new  books = 16 x $12.50

                                                                                  =  $200

Hence Total amount earned by Ryan

= Amount earned by selling old books + Amount by selling new books

=  $137.5 +  $200

= $337.50

or,  Total amount earned by Ryan = $337.50

Hence Ryan's  revenue last month if he sold 16 new books and 25 old books  is  $337.50.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
