staples sells boxes of pens ($10) and rubber bands($4).
Leona ordered a total of 24 cartons for $210.
How many boxes of each did Leona order?
-----
Equations:
Quantity Eq:: p + b = 24 cartons
Value Eq:: 10p + 4b = 210 dollars
------------------------------------
Modify for elimination of the "p" terms.
------
10p + 10b = 240
10p + 4b = 210
-----
Subtract and solve for "b"::
6b = 30
b = 5 (# of boxes of bands)
----
Solve for "p"::
p + 5 = 24
p = 19 (# of boxes of pens)
------
