The cafe charges an initial fee to use the computer and then an additional price per minute of usage. The initial charge to use the computers is $4 and the total charge would be $6 for 5 minutes of use. This is expressed as

5t + 4 = 6

5t = 6 - 4 = 2

t = 2/5 = 0.4

It means that the charge per minute would be $0.4

Therefore, the equation for the function C(t), representing the total cost of using a computer for t minutes at the internet cafe is

C(t) = 0.4t + 4

A quantity b varies jointly with c and d and inversely with e. When b is 18, c is 4, d is 9, and e is 6. What is the constant of

Fantom [35]

B $\alpha$ $\frac{cd}{e}$
b= $k \frac{cd}{e}$
Where k is a constant of proportionality.
b=18, c=4,d=9, e=6
Finding the value f k,
18= $\frac{k*4*9}{6}$
6k=18
k=3
The equation then is;
b= $\frac{3cd}{e}$
The constant of variation=3
