The Franklin Lee Middle School Glee Club is hosting a Talent Show competition to raise money for a community that was recently hit by a flood. All the members are asked to go out in the community to sell tickets to the show. ● Patrick sold 30 more tickets than Jose.
● Gabriella sold 25 less than two times the amount Patrick sold.
● Owen sold a third of the amount of tickets than Patrick sold.
● Desmond sold 15 less than Owen.
If Jose sold 30 tickets, how many tickets did each of the others sell?

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
