It costs 261 for 3 nights at pavia pavilion hotels at the same rate how much will it cost to stay for 7 nights.

There's two ways I can see someone doing this:

The first way requires you to work out the price of 1 night, and multiply that price by 7. So you would do 261 ÷ 3 = 87 (price) and 3 ÷ 3 = 1 (nights). So now you know that per night, it costs 87. Multiply this by 7 to get 609 as the total for 7 nights.

The second method requires you to work out 7 ÷ 3, which is 2.33333333... Multiply 261 by 2.33333333 to work out how much it is for 7 nights. (Also 609). 

The first method however is a lot simpler and sometimes more accurate, because as we found in this example, we didn't encounter any decimals to get the answer. 

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

The correct answer is .44
