Problema Solution
a woman bought some large frames for $15 each and some small frames for $4 each at a closeout sale if she bought 17 frames for $112, find how many of each type she bought
Answer provided by our tutors
Let 'x' represent the cost of small frames, then '17-x' represents the cost of the large frames:
112=4x+15(17-x)
x=13
17-13=4
So 4 large frames were purchased and 13 small frames were purchased.
