Victoria is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. It is known that the total charge to use a computer for 5 minutes would be $6 and that the additional rate per minute of use is $0.60. Write an equation for C, commaC, in terms of t, commat, representing the total cost of using a computer for tt minutes at the internet cafe.
The initial fee to use the computer is denoted by A, the additional rate per minute of usage is denoted by B, and the total charge to use a computer for t minutes is denoted by C.
We are given that the total charge to use a computer for 5 minutes is $6, so we can write the equation: C = A + B(5).
The additional rate per minute of usage is given as $0.60, so B = 0.60.
Substituting B = 0.60 into the equation, we have: C = A + 0.60(5).
Simplifying, we get: C = A + 3.
Therefore, the equation for C in terms of t is C = A + 3.
