17/165×$26.40 = $2.72
_____
<em>Comment on the working</em>
We could work this several ways. Perhaps most straightforward would be to determine how many gallons Sally bought last week, and multiply that by the change in price. Or, the number of gallons could be multiplied by the new price per gallon and the difference from the old purchase amount found.
If you look at the numbers, you see that we have effectively done it the first way. The change in price is $0.17 per gallon, and the number of gallons Sally bought is $26.40/$1.65.
1 meter equals 1000 millimeters
to convert meters to millimeters multiply the known meters by 1000
8.5 meters x 1000 = 8500 millimeters
The ratio of the volume of cylinder and cone is 3:1
Because the volume of:
Cylinder = The area of base x height
Cone = 1/3 The area of base x height
