To be able to quickly solve this, we can temporarily make 5.47 into 547
Now, we can divide 547 by 12.

Now, we can round up from 45.5 to get 46.
However, we originally moved our decimal 2 places over, so now we must move it 2 places again.
46 ⇒ 0.46
The correct answer is $0.46
Since there is no diagram this is how I did it. cross multiply and divide.
Answer:
-40+4b
Step-by-step explanation:
You multiply the outside (-4) by the things within the parentheses
Given:
Original price of a TV = $499
Price increased by 15%.

Step-by-step explanation:
Let
x -----> the number of skaters
y -----> the cost for birthday parties
we have the points
(10,107) and (15,137)
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
substitute the values
step 2
Find the equation of the line in point slope form

we have

substitute

step 3
Convert to slope intercept form



step 4
How much would a party for 12 skaters cost?
For x=12 skaters
substitute the value of x in the equation and solve for y
