Answer:
wrong
Step-by-step explanation:
Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.
Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500
Answer:
I think the answer is -8+-4=-12
Answer:
$4748.80
Step-by-step explanation:
First, find the cost with 20% off, by multiplying the price by 0.8
5600(0.8)
= 4480
Find the cost with tax, by multiplying this by 1.06
4480(1.06)
= 4748.8
So, the sale price, including tax, is $4748.80
Answer:
y = x + 1
Step-by-step explanation:
We can see the line is linear so we can write the equation using y = mx + b. The components of the equation are m = slope and b = y-intercept. We can see from the graph that the y-intercept is 1 as the graph crosses the y axis at y = 1 and if we do 
or 
, we can plug in the y-intercept's coorinates and the point in red's coordinates to get the slope of 1. Therefore, the equation would be y = 1x + 1 or y = x + 1
