Answer :

A rule or regulation that clarifies the connection between two variables is what is meant by a function. The function is a mathematical phrase, rule, or law that establishes the relationship between an independent variable and a dependent variable (the dependent variable).

These variables are referred to as;

  • The unrelated factor
  • The reliant element

The function is;

C = 109 + 55(h) (h)

Where;

The amount of credit hours taken determines the cost for the first semester, C, in dollars.

Change the value of C.

1254 = 109 + 55h

Assemble similar terms

55h = 1254 - 109

55h =1145

h = 20. 8

Therefore, 20.8 hours is the result.
