Problem
A food company distributes its tomato soup in two cans of different sizes. For the larger can, both the diameter and the height have been increased by 15%.
By what percentage does the volume increase from the smaller can to the larger can? Round your answer to the nearest percent.
Solution
the volume of a cylinder is given by:

We know that the diameter=radius and the height are increased by 15% so then the new volume can be calculated on this way:

And the new volume would increase about 52%
-5x = - 7 because -6x plus x is -5x and use elimination to get rid of the -3y so you end up with -5x = -7
6/100× $85.25
x=$511.50 divided by 100
x=$5.1150 Or $5.12
rounded to the nearest cent
Write it as a mixed fraction 7/5 = 1 2/5
