A survey is valid, if it measures what it is designed to measure. And the answer is c. is the correct answer. Hope it helped you!
At a price of $0.50, the amount of cups of lemonade that Caroline and Emily sell when the temperature is 60 degrees than when the temperature is 80 degrees is <u>-</u><u>1</u><u>5</u>.
50 - 80 = -30
= -30 * 0.5
= - 15
<h3>How does one arrive at the answer?</h3>
This is an instance of demand curve shift which refers to key changes in the balance of supply and demand that alter the quantity demanded at the same price. Hence, the shift in the quantity demanded will affect the amount of cups of lemonade that is sold.
Sometimes questions that involve graphs will ask you to consider the effect of a changing factor or factors. Problem statement: the line labeled D1 in the graph to the right shows the number of cups of lemonade that Caroline and Emily can sell at their lemonade stand at various prices.
Caroline and Emily have noticed that they sell more lemonade when it's hotter. Click anywhere on the graph to open a window with a control labeled Temperature. If you use the slider to change the temperature, the line will shift. Change the temperature from 80 degrees to 50 degrees.
At a price of $0.50, the amount of cups of lemonade that Caroline and Emily sell when the temperature is 60 degrees than when the temperature is 80 degrees is<u> -15</u>.
Therefore, the correct answer is as given above

The number of each type of book is what is unknown, so we can represent those quantities with variables. Let x = the number of hardbacks and y = the number of paperbacks. Then we know that: x + y = 65 (the total number of books sold) We also know the total cost of both editions, which is $1356. It can be written algebraically as: 28x + 12y = 1356 We now have a system of two equations, which can be solved by substitution. It would be easier to solve the first equation for either x or y and substitute that into the second equation.
Answer:
Variable cost per unit= $0.10
Explanation:
Giving the following information:
Cost Machine Hours
March $3,106 15,176
April 2,668 9,558
May 2,892 11,947
June 3,538 17,899
<u>To calculate the variable cost under the high-low method, we need to use the following formula:</u>
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (3,583 - 2,668) / (17,899 - 9,558)
Variable cost per unit= $0.10
Answer:
$55
Explanation:
The earnings per share indicate the profit per outstanding stocks and it is calculated by dividing the net income by the number of shares of outstanding stocks. According to this,
Earnings per share= $27,500/500
Earnings per share= $55
Wild Trails Inc.'s earnings per share (EPS) is $55.
