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,C, in terms of t,t, representing the total cost of using a computer for tt minutes at the internet cafe
We know that the initial fee is a constant cost. Let's represent this initial fee as A.
We also know that there is an additional charge per minute of usage, which is $0.60. Let's represent the additional charge per minute as B.
The total charge to use the computer for 5 minutes is $6. This can be written as an equation:
A + 5B = 6
To represent the total cost of using a computer for t minutes, we need to calculate the additional charge for t minutes and add it to the initial fee. The additional charge for t minutes is B times t, and the equation becomes:
C = A + Bt
