Answer the following question, with explanation first.
Bart fills out surveys to earn money. He receives $0.2 for every question he answers in the survey. Each survey has 10 questions. On Monday he finished 3 surveys, and on Tuesday 4 surveys. How much money did he earn during these two days?

14
On Monday and Tuesday Bart finished 3 + 4 = 7 surveys.

Each survey has 10 questions, so he answered 10 * 7 = 70 questions.

Bart gets paid $0.

2 for each questions, so he earned 70 * $0.

2 = $14.

.

Final answer: 14
