Answer:
Your answer should be $29.40
Step-by-step explanation:
If you divide 21 by 5 you get 4.2, so each book costs $4.20.
4.2 x 7 = 29.4
Therefore, your total cost for 7 books will be $29.40
I hope this helps!
First replace x and y by 3 and 4.
(3*(x)+1)/(4*(y)^2)
((3*(3))+1)/(4*((4)^2)) = (9+1)/(4*16) = 10/64 = 5/32.
5/32 is your answer.
