For the opening night at the Opera House, a total of 1000 tickets were sold. Front orchestra seats cost $70 apiece, rear orchestra seats cost $50

apiece, and front balcony seats cost $30 apiece. The combined number of

tickets sold for the front orchestra and rear orchestra exceeded twice the

number of front balcony tickets sold by 400. The total receipts for the

performance were $50,000. Determine how many tickets of each type were

sold?

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
