Answer:
$30
$90
Step-by-step explanation:
Given parameters:
Selling price of belt = $120
Percentage discount = 25%
Unknown:
Discount = ?
Sale price of the dress = ?
Solution:
Discount is a reduction in the price of a commodity.
Discount = percentage discount x selling price of belt
Input the parameters and solve;
I. Discount =
x 120 = $30
II. Sale price of the dress;
= selling price - discount amount
= $120 - $30
= $90
Axis of symmetry = x = -b/2a
where y = ax² + bx + c
f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3
g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0
h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1
least : f(x) = x² + 6x - 1 ; axis of symmetry is -3
middle : g(x) = -x² + 2 ; axis of symmetry is 0
greatest : h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
The answer is 122 as it’s divided
To find the total of a percentage of a number you would multiply the number by the given percentage so in order to find the number that the percentage was found with you would divide the percentage with the percentage found from the number.... 3.5/5% which should come out to be 70. To check you multiply 70 by 5% and get 3.5
<span>Let P be the cost per pound of peanuts.
Let M be the cost per pound of M&M's.
We can set up two equations to solve this question.
(1) 8P + 5M = 55.27
(2) 6P + 4M = 42.70
Let's multiply equation (1) by 3.
Let's multiply equation (2) by 4.
(1) 24P + 15M = 165.81
(2) 24P + 16M = 170.80
Let's subtract equation (1) from equation (2).
M = 4.99
Let's put M = 4.99 in equation (2) to find P.
6P + 4(4.99) = 42.70
6P = 42.70 - 19.96
6P = 22.74
P = 22.74 / 6
P = 3.79
The cost per pound of peanuts is $3.79
The cost per pound of M&M's is $4.99</span>
