Pleass ! will give brainliest and worth 50 points! four workers each earn the same hourly rate and were paid a total of $45 for doing yard work. part a express one worker's pay as a rational number in simplest form. part b express the rational number in part a as the product of a rational number and a whole number. part c covert the rational number in part a to a decimal using long division. show or explain your work. part d if the four workers completed the yard work in 20 minutes, what is the hourly rate for each worker? show or explain your work.

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
