An environmental engineer need to blend a single mixture of insecticide spray of volume V=2 litres and concentration C=0.27 from two solutions having concentrations c1=0.11 and c2=0.38 . If the volumes of each solution are v1 and v2 we have the following system of equations: v1+v220.11v1+0.38v2=0=0.54 Find the volumes v1 and v2 of the solutions required to make up the mixture. Give your answer correct to 3 decimal places and show full working
