Sagot :
Answer:
x = 8 minutes
Step-by-step explanation:
Given that,
An internet cafe charges a fixed amount per minute to use the internet.
The cost of using the internet in dollars is,
[tex]y=\dfrac{3}{4}x[/tex]
Where
x is the number of minutes spent on the internet
We need to find the value of x when y = $6.
So, put y = 6 in the above equation.
[tex]6=\dfrac{3}{4}x\\\\x=\dfrac{6\times 4}{3}\\\\x=8\ min[/tex]
So, 8 minutes must spent on internet.
