400/12 = # of dozen needed
.89 * # of dozen needed
400/12=33.33 need 34 dozen
.89*34=$30.26
5m^2 x 2m = 10m^3
60cf/3f = 20cf^2
15c-5f/2 = Cannot be simplified further
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286
