American airlines had a flight going out later that day. they charge $53 dollars for each first class ticket, and $21 dollars for each coach ticket. there were 139 passengers total.30% of the passengers composed of the first class. how much money did american airlines make total?

American airlines made a total money of $ 4263

Solution:

Given that,

Cost of 1 first class ticket = $ 53

Cost of 1 coach ticket = $ 21

There were 139 passengers total

30% of the passengers composed of the first class, Which means 30 % of 139 are first class

Number of first class passengers = 30 % of 139

Thus approximately 42 passengers are from first class

Number of coach class passengers = 139 - 42 = 97

So we have,

Number of first class passengers = 42

Number of coach class passengers = 97

To find: Total money made by American airlines

We can frame a equation as:

total money = (Number of first class passengers x Cost of 1 first class ticket) + (Number of coach class passengers x Cost of 1 coach ticket)

Thus american airlines made a total money of $ 4263

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
