Subtract the original value from the new value, then divide the result by the original value. Multiply the result by 100. The answer is the percent increase. Check your answer using the percentage increase calculator. Working out the problem by hand we get: [ (1,445 - 1,250)/1,250] * 100. (195/1,250) * 100.

Pigments and dyes both change the perceived color of an object by altering reflected and absorbed light – the varying wavelengths of light that are reflected produce the color that is seen. Both have also been used for thousands of years. Textile dyeing dates to at least 65,000 years ago, while evidence of pigment usage has been traced back ...

In New England, the common practice is to mix the residues, run them through an attrition mill to comminute them to a smaller size, and then dry them in a rotary, multipass drying system. Freezing turns the rubber granules into a glass-like state that fractures easily during grinding in a high-speed attrition mill.
