Baird and lon earned points for the number of books and magazines they read over the summer. the average of the two boys’ points can be expressed as , where p represents the number of points earned per book. (5.4p+5) + (8+3.2p)/2 what is the average when p = 3?

The average is 19.4

Step-by-step explanation:

(5.4p+5) + (8+3.2p)/2

where p = 3 which means whenever you see p, represent it with 3

{(5.4(3)+5) + (8+3.2(3)}/2

(16.2 + 5) + (8 + 9.6)/2

combine within the bracket

(21.2) + (17.6)/2

combine both bracket

38.8/2

19.4

The average is 19.4

Hope this helps!
