To answer this question, we are going to write a system of linear equations into variables and solve.
00:09
I've already defined the variables that i will use on the screen.
00:14
So let's write our equations.
00:17
The 20 in the first sentence is not needed.
00:21
15 ounces of peanuts and 5 ounces of cashews is already 20.
00:26
We don't need to incorporate the 20.
00:28
So my first equation could be 15 ounces of peanuts times cost per ounce plus five ounces of cashews times cost per ounce was $6.
00:44
On the other hand, five ounces of peanuts plus 15 ounces of cashews was $8.
00:53
So cashews must cost a little bit more per ounce.
00:58
Next, i am going to need to eliminate a variable.
01:09
I'm going to multiply that i'll eliminate c...
