Zoya has to earn at least $300 to meet her fundraising goal. She has only 100 bracelets that she plans to sell at $5 each. Which inequality shows the number of bracelets, x, Zoya can sell to meet her goal?

Answers

Call the number of bracelets sold x. Gvien that there are 100 bracelets: x < or equal than 100 Earnings = 5x => 5x > or equal than 300 => x > or equal than 300 / 5 => x > or equal than 60. Then, you obtain 60 < or equal than x < or equal than 300.

Answer:

Amount needed by Zoya to meet her fundraising goal ≥ $ 300

Number of Bracelets possessed by Zoya = 100

Cost of single bracelet = $ 5

To meet her goal , we need to convert these statement into equation

Let number of Bracelets sold = x

1. x≤ 100

2. 5 x ≥ 300

Dividing both sides by 5, we get

x ≥ 60

The two inequality are : x ≤  100 and x ≥ 60

So the inequality is : 60 ≤ x≤ 100.

If (-7,y ) is a solution to the equation 2x -7y = 42, what is the value of y?I don't think this problem is worded right or something?
Please help

Answers

they mean -7 is the x value so you plug that into the equation 
-14 - 7y = 42
-7y = 56

The Hamilton Brush Company issued 2,500 shares of common stock worth $100,000.00 total. What is the par value of each share? A. $40.00 B. $250.00 C. $400.00 D. $25.00

Answers

Given:
2,500 shares of common stock
$100,000.00 total value

Find the par value of each share.

Par value is the value written on each certificate of stock.

We get the par value by dividing the total value of the common stock by the total number of shares of common stock.

$100,000 ÷ 2500 shares = $40 per share

The par value of each share is $40.00

The par value of each share is calculated as $40 which is option A

What is the par value of each share?

To find the par value of each share, we divide the total value by the number of shares. In this case, the Hamilton Brush Company issued 2,500 shares worth $100,000.00 in total.

$100,000.00 divided by 2,500 shares gives us $40.00.

Mathematically;

1000000 / 2500 = 40

Therefore, the par value of each share is $40.00.

The answer to this problem is option A
