A hotel charges a flat rate, x, for each hour a customer uses the internet.
Enter an equation to express the total cost, y, to use the
internet at the hotel for t hours.

tx=y

Step-by-step explanation:

For every hour you spend on the computer is t. So if it cost x per customer then you can just simply multiply x and t. It says y is the total cost so that would be what is equalls to.

Example:

x= $5

t=3 hours

Using these sample numbers we can put them into the equation

3·5=y

15=y

15 dollars in total
