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

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: ouch. thats difficult
