To find the unit price, we need to divide the total cost by the number of units.
Given that an 8-yard roll of white paper costs $2.88, the unit price is $2.88/8 yards = $<<2.88/8=0.36>>0.36 per yard.
Therefore, the unit price of the white paper is $0.36 per yard.

uther is having his birthday party at the Galactic Fun party venue this year. The Blastoff party package costs $215 and covers the entrance fee for guests, a private party room, and model rocket painting. Luther's parents upgraded his package to include a favor for each of his 9 guests, bringing the total to $269. What is the cost of each favor?

$
To find the cost of each favor, we need to subtract the cost of the basic package from the cost of the upgraded package and divide it by the number of guests.
The cost of each favor is ($269 - $215)/9 guests = $54/9 guests = $<<54/9=6>>6 per favor.
Therefore, the cost of each favor is $6.
The cost of each favor is ($269 - $215)/9 guests = $54/9 guests = $<<54/9=6>>6 per favor.
Therefore, the cost of each favor is $6.
Roxanne is measuring the diameter and the radius of different-sized circles. She finds the diameter is always 2 times longer than the radius.
There is a proportional relationship between the radius of the circle in inches, x, and the diameter of the circle in inches, y.
Graph this relationship. Select two points to draw a line.

There is a proportional relationship between the radius of the circle in inches, x, and the diameter of the circle in inches, y.
Graph this relationship. Select two points to draw a line.
What
The proportional relationship between the diameter and the radius of a circle can be represented by the equation:
y = 2x
To graph this relationship, we can plot two points and draw a line that passes through them.
Let's select two arbitrary values for the radius, x:
If x = 1 inch, then the diameter, y, would be y = 2(1) = 2 inches.
If x = 3 inches, then the diameter, y, would be y = 2(3) = 6 inches.
Therefore, the two points we can plot on the graph are (1, 2) and (3, 6).
Plotting these two points and drawing a line that passes through them, we get the following graph:

y | . (3,6)
