Bart earns $0.2 for every question he answers, and each survey has 10 questions.
So for each survey, Bart earns $0.2 x 10 = $2.
On Monday, Bart completed 3 surveys, so he earned 3 x $2 = $6.
On Tuesday, Bart completed 4 surveys, so he earned 4 x $2 = $8.
Therefore, Bart earned a total of $6 + $8 = $14 by completing 3 surveys on Monday and 4 surveys on Tuesday.
#### 14
