355 miles/17 gallons ≈ 20.88 miles per gallon
284 miles ÷20.88= 13.6 gallons needed
3/5 1/6 3/7 2/5
------------------------
In linear change, the two variables keep increasing or decreasing at the same speed.
36 donuts (2 1/2 dozen) = $8.00
So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.
One dozen donuts = $2.64
Just a question, are the 2's squares?
