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

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
