All right, so this question tells us that we can sell 9 ,000 shirts for $44, or we can sell 13 ,000 shirts at $32.
00:12
And we had this equation here that would help us find the pricing that we should put for each shirt depending on the number of shirts.
00:21
So the first thing we want to figure out is m.
00:25
So m is our slope here, and the slope equation is m equal to...
00:31
Y2 minus y1 over x2 minus x1.
00:40
So we would get that information from our information given here by the shirts and the values of the dollars.
00:46
So we can start with 13 ,000 as our y2, minus 9 ,000.
00:58
And we can have 32 since that correlates with the 13 ,000, minus 44 that correlates with the 9 ,000.
01:11
If we simplify this, we should get 5 ,000 i'm sorry 4 ,000 4 ,000 over negative is at 12 let's see if that simplifies that something pretty so it simplifies into 33 .3 3 .3 repeating so let's go with this here just to keep the value simple looking so we have our slope now and now using one of these bits of information we want to to find intercept value so we can plug one using one of these two let's use the 13 ,000 and at 32 dollars for our p and our n and let's solve for our b so we're going to use 13 ,000 our slope which we found over here is negative 4 ,000 over 12 our n since we're using 13 ,000 has to be 32 and then b is what we're looking for 13 ,000 let's see if this simplifies into anything of use for us...
