Answer:
Joanna bought 21 items that come out to a total of $33.33. She bought 9 notebooks and 12 pencils.
Step-by-step explanation:
Notebooks (N) = $1.85 Pencils (P) = $1.39
9N+12P= $33.33
9*1.85=16.65
12*1.39=16.68
16.65+16.68=33.33
3 x 4 = 12
12/12 - 1/3 ( so 4/12) = 8/12
8/12 - 1/4 ( so 2/12 as you only have 8/12 left) = 6/12
Answer = 6/12 = 1/2 or 50%
