Dollar profit in a week when he services 25 lawns.
00:03
He makes $600 profit in a week when he services 11 lawns.
00:08
If the profit for the week is a linear function of the number of lawn service, how much profit would he receive in a week that he has serviced 36 lawns? so i'm going to set up a table first.
00:22
So lawns and then the amount of money, so 600, and then 25 lawns is 2 ,000.
00:32
So i'm going 2 ,000 minus, oops, 600 is 1 ,400, up 1400, and then up 14.
00:48
So my y over x would be $1 ,400 over $14, which would be $100, okay? and then, um, up divided by, okay, so then i have y over $1 ,000.
01:14
Y equals 100x plus b.
01:18
And now i have to figure out what the y intercept is.
01:21
So i'm going to do 600 equals 100 times 11 plus b...
