Question 830365: Danielle and her brother mixed together some soil and some clay to make 10 yd^3 of soil with 84% clay content. They used 6 yd^3 of clay and 4 yd^3 of a soil that they purchased. What was the clay content of the soil that they purchased? Answer by josgarithmetic(39617) (Show Source):
using "units" for "yard^3",
the mixture is 6 units clay plus 4 units soil;
6+4*r=theClay units, where r is a fraction in DECIMAL form. That is the mixture according to the purchased used quantities of clay and soil.
The first part of the description gives 10*0.84 units of clay, for the resulting mixture.
UnitsOfClayKnown=UnitsOfClayMixed
If this makes sense, then GOOD.
