An airline charges $150 for an economy class seat, $450 for a business class seat, and $600 for a first class seat. There are three times as many economy class seats as business class seats on an airplane. The revenue from selling all 60 seats on the airplane is $15,000. How many of each type
of seat does the airplane have?

step-by-step explanation: 4 cause 2+2=4

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
