The sorptivity is widely used in characterizing soils and porous construction materials such as brick, stone and concrete. Calculation of the true sorptivity required numerical iterative procedures dependent on soil water content and diffusivity.
The refrigerator is on sale for $1,200 and her sales tax rate is 6%. 1,200 multiplied by 0.06 is 72, so Sarah would pay $72 in sales tax. This would bring her total bill to $1,272.
