a video store received two shipments of videocassettes. the value of the first shipmetn which contained 8 short and 16 long was $224 the value of the second which contained 6 short and 18 long casseetes was $228 find the price of one long cassette
-------------------
Equations:
8s + 16L = 224
6s + 18L = 228
----
Get rid of the s terms.
---
s + 2L = 28
s + 3L = 38
---
Subtract to get:
L = $10
