April buys 8 books for $44.1 paper back book costs$4 and 1 hard back book costs $8. how many of each did she buy? (use an equation to solve)
p > paperback books
h > hardcover books
use these equations to solve
p + h = 8
4p + 8h = 44

h = # of hardback books
p = # of paperback books
h + p = 8 = h = 8  p
4p + 8h = $44
4p  4h = 32
4p + 8h = 44
4h = 12
 
4 4
h = 3
Answer: 5 paperback books and 3 hardback books
