Answer:
Option A)

Step-by-step explanation:
We are given the following in the question:
Cost of orange/black shirt = $15
Cost of black/white shirt = $10
Amount of money to be raised is atleast $1000.
Let x be the amount of orange/black shirt and y be the amount of black/white shirt.
Thus, we can write the inequality:

That is the total cost of orange/black shirt and black/white shirt should be greater than or equal to $1000.
Thus, the correct answer is
Option A)

d = 3 , a₁₂ = 40 and S
= 7775
In an arithmetic sequence the nth term and sum to n terms are
<h3>• a

= a₁ + (n-1)d</h3><h3>• S

=

[2a + (n-1)d]</h3><h3>
where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ =

[(2×7) +(99×3)</h3><h3> = 25(14 + 297) = 25(311)= 7775</h3>
The inequality is all real numbers.
<h3>What is inequality?</h3>
A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
|3x|≥0
3x = 0
Divide both sides of the equation by the coefficient of variable
x= 0/3
x=0 = RHS
