The graph shows the number of airplanes that flew out of an airport last week

Mon=4airplanes
Tues=7airplanes
Wed=3airplanes
Thu=8airplanes
Fri=5airplanes

If each airplane carried 120 people then how many people flew out of the airport last week?
A.3240
B.3140
C.1080
D.880
B?

Not quite.

Right. A is correct.

To find the total number of people who flew out of the airport last week, we need to multiply the number of airplanes on each day by the number of people carried by each airplane.

Monday: 4 airplanes * 120 people/airplane = 480 people
Tuesday: 7 airplanes * 120 people/airplane = 840 people
Wednesday: 3 airplanes * 120 people/airplane = 360 people
Thursday: 8 airplanes * 120 people/airplane = 960 people
Friday: 5 airplanes * 120 people/airplane = 600 people

Now, we can sum up the number of people on each day to find the total:

480 + 840 + 360 + 960 + 600 = 3240

Therefore, the correct answer is option A. 3240 people flew out of the airport last week.
