PROBLEM #30
Henrietta designs websites for individuals and businesses.
Since she charges a $50.00 consultation fee plus $24.00 per
hour in labor, a funcdon that would describe her charges would
be
C(h) = 24h + 50
where C(h) is the cost function for the number of hours, h.
a) How much would Henrietta charge a client for a job that takes
13 hours? Show your work.
b) How many hours did Henrietta work if she charges a client
$542.00? Explain and show how you get your answer.

a +

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

b

step-by-step explanation:

b mark me branliest thx

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
