One measure

$(25pts)$ It is desired to reduce the density of a Class A cement to $12\mathrm{.}8lb\frac{m}{g}al$ by adding bentonite. Using the water requirements for Class A cement and bentonite given in Table $4\mathrm{.}5,$ compute the weight of bentonite that should be blended with each sack of cement. Compute the yield of the slurry. What is the "percent mix" of the slurry?

Note: SG of cement$=2\mathrm{.}65$; SG of bentonite$=3\mathrm{.}14$; $1$ sack of cement$=94$ lbm;
