Question

A nurse mixes 60 cc of a 50% saline solution with a 10% saline solution to produce a 25% saline solution. How much of the 10% solution should he use?

Answer 1

100 cc

100 cc of the 10% solution should be used.

50%(60)+10%(x)=25%(60+x)

0.5(60)+0.1(x)=0.25(60+x)

30+0.1x=15+0.25x

30-15=0.25x-0.10x

15=0.15x

1500=15x

x=1500/15

x=100 cc
