So first we're starting off with a $10 bill.
00:03
Ultimately, these problems help us set up equation.
00:05
So let's try to set up an equation rather than just thinking, guess about it.
00:09
So we have a $10 bill.
00:10
That's $10 credit, so positive money, minus $3 .25 spent on ice cream, plus 0 .96 spent on 1 .5 pounds of meat.
00:34
And we know that um, ultimately if the change was 96 cents, oh, so we actually wanted, the change was 96 cents.
00:46
So it's going to be 1 .5 times, uh, x the price per pound equals 0 .96.
00:59
So what we end up getting with that is, uh, we subtract 10 and then we divide by the negative.
01:08
So we have 0 .10 minus.
01:12
0 .96.
01:13
So that's going to be $9 .4 .4 equals 325 plus 1 .5x.
01:23
Then we're going to subtract 3 .25, and then divide the whole thing by 1 .5, and we get x equals $3 .86 per pound...
