a 1.25L Coca Cola that cost $1.29
Unit rate means we need to find the rate of 1 liter of Coca Cola
1.25 L Coca Cola = $1.29
1 L of Coca Cola = ?
To find 1 liter of Coca cola divide the cost by liter, so we divide 1.29 by 1.25
1.032
So the cost of 1 liter of Coco Cola = $1.032
as you already know, a direct proportional variation has a constant of variation "k", y = kx, which in this case that'd be the slope, namely 15.
