The better option is to buy the Granola bar.
What is a unit value?
When the expenditures or value of production of an item is divided by the quantity, the result is known as a unit value. The unit value of a set of homogeneous products is the total value of the purchases/sales divided by the sum of the quantities.
To determine which is the better buy, you need to compare the price per granola bar for each option. To do this, you can divide the price of each pack by the number of granola bars it contains.
For the first pack of 100 granola bars, the price per granola bar is $8.67 / 100 granola bars = $0.09 per granola bar.
For the second pack of 50 granola bars, the price per granola bar is $5.48 / 50 granola bars = $0.11 per granola bar.
Since the price per granola bar is lower for the first pack, it is the better buy. You would save money by purchasing the first pack of 100 granola bars instead of the second pack of 50 granola bars.
Hence, the better option is to buy the Granola bar.

Which equation is written in slope-intercpet form and has a slope of -5 and a y intercept of 5?
The equation written in slope-intercept form withn a slope of -5 and a y-intercept of 5 is y = -5x + 5
What is an intercept?intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
equation of straight line in slope intercept form is given as
y = mx + c
where m = slope and c = y-intercept
from the question, it means m = -5 and c = 5
substituting we have,
y = -5x + 5

What is an equation?
In mathematics, an equation is a formula that expresses equality by connecting two expressions with an equal sign. Equations and their cousins in other languages may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, whereas in English any well-formed expression consisting of two expressions joined by an equal sign is an equation.
To solve an equation involving variables, it is necessary to determine which values of the variables make the equation true. The variables for which the equation must be solved are also called unknowns, and the values of the unknowns that satisfy the equation are called the solution of the equation. There are two types of equations: identities and constraints. The ID applies to all values of the variable. Constraint expressions apply only to specific values of variables.

V = 6 units³
SA = 22 units²
Dilated solid:
V = ?
SA = 198 units²
The ratio of the areas is 198/22 = 9
The ratio of the area is the square of the scale factor.

How to find the angles of a triangle?The triangle ABC is a right angle triangle because it has one angle as 90 degrees. The sum of the angles in the triangle is 180 degrees.
The angle ECD is congruent to angle ACB(vertically opposite angles).
Therefore,
∠ECD ≅ ∠ACB
Hence,
x = 180 - 90 - 22
x = 68 degrees.
using trigonometric ratios, let's find y
cos 22 = adjacent / hypotenuse
sin 22 = 2y - 1 / 15
cross multiply
15 cos 22 = 2y - 1
2y - 1 = 13.9077578185
2y = 13.9077578185 + 1
2y = 14.9077578185

How will the act be popular paid for their performance?The total amount that should be paid is the sum of the single appearance fee, the 20% of ticket sales and the 10% of concession receipts.
We have,
single appearance = $250,000
sales =$1,250,000
concession receipts = $400,000
Total amount = single appearance + (10% of sales) + (10% ofconcession receipts)

How to find m∠T in the triangle?
The congruence of any two figures is generally understood as two figures which can perfectly overlap each other. Congruent triangles are triangles that are perfect copies of one another.
Given: ΔABC and ΔRST
If the two triangles ABC and RST are arranged, two angles and a side of one are respectively equal to two angles and the corresponding side of the other (AAS). Thus, the triangles are congruent. This implies:
∠A = ∠R, ∠B = ∠S, |AB| = |RS| .Also, ∠C = ∠T, |AC| = |RT| and |BC| = |ST|
Thus, <R = 41°, ∠S = 74°,
<R + ∠S + ∠T = 180° (Sum of angle in a triangle)
41 + 74 + ∠T = 180
115 + ∠T = 180
∠T = 180 - 115
∠T = 65°
