Question 1012424
Call the cost of a pound of jelly beans, j.
Call the cost of a pound of trail mix, t.
Then we can write two equations...we will work in cents...
3j + 8t = 2300
5j + 2t = 1000
Let us multiply the bottom one by four and subtract it from the top one...
3j + 8t = 2300
-(20j + 8t = 4000)
--------------------
-17j = -1700
j = 100 ($1.00 a pound for jelly beans)
Now plug that in to the first equation and get
3(100) + 8t = 2300
300 + 8t = 2300
8t = 2000
t = 250 ($2.50 a pound for trail mix)
