In this problem, we're talking about the calories that would be in a slice of two different types of pies.
00:08
And we're told that in a slice of pecan pie, the amount of calories would be 221 less than twice the amount in a slice of lemon meringue pie.
00:20
And if you have one piece of each, you would be consuming 865 calories.
00:26
So i'd like to start out.
00:28
We're basically asked to determine the number of calories in each slice.
00:32
Each piece of pie.
00:34
So i like to start out by defining or identifying my variables.
00:39
So i'm going to let p equal the number of calories in a slice or a piece of pecan pie.
00:55
And i will use l to represent the same thing for a piece of lemon meringue pie.
01:17
I was sorry, i didn't write piece there, but this would be a piece of lemon meringue pie.
01:23
High.
01:25
And then using the kind of first little sentence that i have there, pecan is, so p equals 221 less than.
01:36
So that means that you're going to be taking something and subtracting 221 from that.
01:42
And that's something that we're subtracting it from is twice the amount of lemon meringue...
