Eden and Courtney each have a bag of candy. There is a mixture of chocolate and sour candy. Eden has a total of 5 pieces of candy. 2 are sour. Courtney has 10 pieces of candy. How many sour pieces does Courtney have if she has the same fractional amount of sour candy as Eden?

what is the answer to this

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

110

based on the question i am guessing that it is a typo for abc
