Question 4

A luthier uses different special blends of oil varnishes to finish different instruments. In her workshop, she keeps a 30% strength and a 80% strength version of her favorite varnish product. To finish a viola she has just made, she wants to apply a 50% strength version of the varnish. She will need 1000 mL of the mixture to finish the viola.
Let m be the number of milliliters of 80% strength product. Choose an equation to match the situation.

0.5(1000)=0.3(1000-m)+0.8m

0.5(1000)=0.3(1000+m)-0.8

0.5(1000)=0.8(1000-m)+0.3m

0.5(1000)=0.8(1000+m)-0.3m
