You earn $17.50/hr and work 40 hr/wk. your deductions are fica (7.65%), federal tax withholding (12.3%), and state tax withholding (6.2%). your housing and fixed expenses are 30% of your realized income per month. you want to save 5 months' worth in an emergency fund within a year. how much do you need to save per month to fund the emergency fund?

a. $249.03

b. $271.10

c. $258.48

d. $396.62

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

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
