Respuesta :

Answer:

a. The constant of proportionality is, 21

b. Tiana charges $94.50 for a job, so, c=94.50

from the given equation,

c = 21h

or, 94.50 = 21h

or, h = 94.50/21

or, h = 4.5

She babysit for 4.5 hours.

  1. The constant of proportionality is 21 and it means the constant value that connects two variables together.
  2. If Tiana charges $94.50 for a job, she spent 4.5hours babysitting.

  • The equation used by Tiana c = 21h to figure out the total amount (c) she should charge a customer for babysitting for h hours.

  • The constant of proportionality, denoted by K, in a linear relationship shows how two variables relate to one another. In this case, the total amount (c) is directly proportional to time (h).

  • The constant of proportionality, which is 21, connects the variables 'c' and 'h'.

  • If Tiana charges $94.50 for a job, we can calculate the time spent on doing the job by using:

c = 21h

94.50 = 21h

h = 94.50 ÷ 21

h = 4.5hours.

Therefore, Tiana spent 4½ hours babysitting.
