What is an expression for every 2 hours you get 20 dollars

10/1 x 2 = 20

Step-by-step explanation:

By using this expression you can show daily, weekly yearly exactly the same, take 40hrs , then 52 weeks and even 17 overtime extra days.

weekly      20/2 x 40 = 10 x 40 = 400

yearly        20/2 x 40 x 52 = 400 x 52 = 20800

overtime    20/2 x 17 = 170

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
