Here, we're given a situation where the monthly sales are currently at 580 ,000, and they decrease 4 ,000 per month.
00:12
Now, this equation says we want to estimate the change in monthly sales over the next five years.
00:18
Okay, so if we have 580 ,000 and they are currently decreasing at 4 ,000 per month, so let's just say x.
00:36
Then we could say the sales, let's just call that y, is going to be about 580 ,000 minus 40x, 40 ,000 x.
00:47
We want to estimate the change in monthly sales over the next five years.
00:51
So if i just say, well, over five, that's going to be five times that 4 ,000...
