Step-by-step explanation:
The expression for Total cost is ( 3h + 2p ).
Where ' h ' represents ' hardcover books ' and ' p ' represents ' paperback books '.
From the question, h = 6 and p = 4
All we need to do is substitute the value of ' h ' and ' p ' given to us in the expression 3h + 2p.
Therefore we have ;
Total cost = 3(6) + 2(4)
= 18 + 8
=26
Therefore Total cost is $26 since the question asks us to present the answer in dollars.
