Okay, so in our scenario, rebecca matt, work at a small restaurant.
00:05
As a waitress, rebecca's daily wage is $50, and she gets to keep 75 % of the tips.
00:09
As a cook, matt's daily wage is $65, and he keeps 25 % of the tips.
00:13
So if we want to write a system of equations, we've got two things going on.
00:18
We want to model both one for rebecca and one for matt.
00:21
So rebecca's wages are going to call w.
00:24
Okay.
00:25
So w will be, let's write that here.
00:27
W will be the total wages for a day.
00:32
T is going to be the amount of tips in the day.
00:35
Okay? so her wages are made up of $50 plus 0 .75 times the amount of tips.
00:43
That's the 75 % there.
00:45
Matt is making $65 a day plus 0 .25 times tips.
00:51
Okay.
00:52
So that means we can take these, we'll take these together.
00:55
If we're finding out when do their, when are their wages the same? okay.
01:02
So we're going to find out how much tips must be collected in order for them to have the same wages...
