Kirchhoff's Junction Rule Practice Test

Using Kirchhoff's Junction Rule, determine $I_2$ leaving junction D if $I_1=0.80,\text{A}$ enters and $I_3=0.25,\text{A}$ and $I_4=0.15,\text{A}$ leave.

Solve for the unknown current $I_3$ entering junction C if $I_1=1.20,\text{A}$ and $I_2=0.45,\text{A}$ leave junction C, and $I_4=0.30,\text{A}$ enters.
