Candy's Sweets Company charges $1.15 per pound to ship candy.
Part A: Write an equation to determine the total cost, c, to ship p pounds of candy. Use your equation to determine the cost of shipping 2 pounds of candy. (6 points)
Part B: If the company reduces the cost to ship candy by $0.25 per pound, write an equation to determine the total cost, c, to ship p pounds of candy with the reduced cost. (4 points)
Answer:
Part A: c = 1.15p
c = 1.15(2) c = 2.30
Part B: c = 0.9p
c = 0.9(4) c = 3.60
Answer:
Part A: c = 1.15p; The cost of shipping 2 pounds of candy is $2.30.
Part B: c = 0.9p
Step-by-step explanation:
Part A:
$1.15 --- 1 pound
$1 --- 1.15 pounds
Replace the money sign with c (since c represents the total cost) and replace pounds with p (since p represents pounds of candy)
c = 1.15p
We can then use this equation to find the c (cost) for 2p (2 pounds).
c = 1.15(2)
= 2.30
Thus, the cost of shipping 2 pounds of candy is $2.30.
Part B:
$1.15 - $0.25 --- 1 pound
$0.90 --- 1 pound
$1 --- 0.9 pound
Replace the money sign with c (since c represents the total cost) and replace pounds with p (since p represents pounds of candy)
c = 0.9p

Santiago starts a savings account with $20. Each month he deposits $15 more into the account. Santiago wants to save a least $80. Write an inequality that represents this situation.
Answer:
$20 + $15m ≥ $80
Step-by-step explanation:
He starts off with $20.
He adds $15 each month, so $15m.
He wants to save at least $80, which means greater than or equal to $80. So, you use this symbol: ≥
Put it all together.
$20 + $15m ≥ $80

pleas give me a BRAINLY pleas
Answer:
y = 4[tex](3)^{x}[/tex]
Step-by-step explanation:
For an exponential function in the form
y = a [tex]b^{x}[/tex]
Use the given points to find the values of a and b
Using (1, 12), then
12 = ab → (1)
Using (2, 36), then
36 = ab² → (2)
Divide (2) by (1)
[tex]\frac{36}{12}[/tex] = [tex]\frac{ab^2}{ab}[/tex] , then
3 = b
Substitute b = 3 into (1) for value of a
12 = 3a ( divide both sides by 3 )
4 = a
Thus
y = 4[tex](3)^{x}[/tex] ← is the exponential function
$16 for 4 books. How much would 12 books cost?
Answer:

How do you inverse 3x-4y=6
Answer:
To find the inverse you switch x and y
Step-by-step explanation:
3y-4x=6
So 3y = 4x+6
and Y = 4/3x + 2
Answer:
y=(6-3x)/-4
Step-by-step explanation:
to get the inverse we make y the subject of the equation
3x-4y=6
-4y=6-3x
y=(6-3x)/-4

Explain whether △ABC is congruent to △XYZ according to the angle side angle (ASA) congruence criteria.
Answer:
∆ABC and ∆XYZ cannot be proven to be congruent to each other according to the Angle-Side-Angle (ASA) Congruence criteria.
Step-by-step explanation:
The Angle-Side-Angle (ASA) Congruence criteria says that two triangles are congruent to each other if two angles and an included side of one triangle is congruent to two corresponding angles and a corresponding included side of the other triangle.
In the diagram given, the two angles were given (<B and <C), however, the side given (side AB) does not lie in the middle of <B and <C, hence it is NOT AN INCLUDED SIDE. The same applies to ∆XYZ.
Therefore, ∆ABC and ∆XYZ cannot be proven to be congruent to each other according to the Angle-Side-Angle (ASA) Congruence criteria.

Solve the equation.
S- (- 20) = 19
Answer:
s = -1
Explanation:
s − (−20) = 19
[ Simplify both sides of the equation ]
s + 20 = 19
[ Subtract 20 from both sides ]
s + 20 − 20 = 19 − 20
s = −1

Deborah spent $70 on food and clothes she spent $26 more on clothes then on food Brighton solve a system of equations to find how much Debra spent on each
Answer:
Step-by-step explanation:
You know the total will be $70.
She bought food, let's call that "F"
She spent $26 more on clothes than food. So her clothes purchase is "F+26".
So let's set-up the equation this way:
food + clothing = Total Spent
F + F + 26 = 70
2F + 26 = 70 (subtract 26 from both sides of the = sign)
2F = 44 (Divide both sides so you find out how much was spent on "F" or food.)
F = 22 (But the question doesn't stop there.)
Deborah spent $22 on food. (Remember, she spent $26 more on clothes, so we have to use our "clothes" equation? ) Deborah spent $48 on clothes. She spent a total of $70 on her purchases.
