1. Whichever option you choose, JUSTIFY YOUR REASONING. To get full
credit, each response should contain at least two (2) full sentences,
which clearly shows your thinking.*

2. For the option that you choose, what will the final cost be? Identify which 20 points
games you would purchase. Write an equation to show how you would
find the final cost. *

3. Ask a family member or friend which option they would choose. Identify 20 points
which games they would purchase. Write an equation to show how you
would find the final cost for your family/friend's choice.

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
