4. A video rental store rents movies at $3.95 for the first night, plus $1.25 for each additional night. When you return your movie, you pay $7.70. How many extra nights did you keep the movie?

3 nights

Step-by-step explanation:

Set up an equation that represents the problem:

y = 1.25x + 3.95

Where y is the total cost and x is the number of additional nights you rent the movie

Substitute:

7.70 = 1.25x + 3.95

Subtract 3.95 on both sides:

7.70 = 1.25x + 3.95

-3.95              -3.95

3.75 = 1.25x

Divide by 1.25 on both sides:

3.75 = 1.25x

/1.25    /1.25

3 = x

Therefore, you kept the movie for 3 additional nights.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
