Carolyn and Kim are selling lemonade this summer.
It costs 10 cents to make each cup of lemonade.
They are going to sell each cup of lemonade for 25 cents.
What is the total cost to make 55 cups of lemonade?
If they sell 55 cups of lemonade, what is the amount of money they will collect?
If they sell 55 cups of lemonade, how much more money would they collect than they would spend?
What is the least number of cups of lemonade they need to sell in order to collect $10.00 more than the spend?
cost: .10*55 = ?
revenue: .25*55 = ?
profit: (.25-.10)*55 = ?
to get $10.00 profit,
.15n = 10.00
n = 66.7, or 67 cups
To find the total cost to make 55 cups of lemonade, we need to multiply the cost per cup (10 cents) by the number of cups (55).
The calculation would be:
Total cost = Cost per cup * Number of cups
Total cost = 10 cents * 55 cups
To calculate this, you can multiply 10 by 55 using pen and paper or using a calculator.
The result is $5.50. So, the total cost to make 55 cups of lemonade is $5.50.
Next, let's calculate the amount of money they will collect if they sell 55 cups of lemonade.
Since each cup of lemonade is being sold for 25 cents, we can multiply the selling price per cup (25 cents) by the number of cups (55) to find the total amount collected.
The calculation would be:
Total money collected = Selling price per cup * Number of cups
Total money collected = 25 cents * 55 cups
Again, you can use pen and paper or a calculator to multiply 25 by 55.
The result is $13.75. So, if they sell 55 cups of lemonade, they will collect $13.75.
To find the difference between the amount of money they will collect and the total cost to make the lemonade, we can subtract the total cost from the total money collected.
Difference = Total money collected - Total cost
Difference = $13.75 - $5.50
Subtracting $5.50 from $13.75, we get $8.25. So, if they sell 55 cups of lemonade, they will collect $8.25 more than they would spend.
Finally, let's determine the least number of cups they need to sell in order to collect $10.00 more than they spend.
First, we can set up an equation:
Total money collected - Total cost = $10.00
Using the variables, let's define the number of cups of lemonade as "x."
25x - 10x = $10.00
Combining like terms gives us:
15x = $10.00
To solve for "x," we divide both sides of the equation by 15:
x = $10.00 / 15
Using a calculator or by long division, we find that x is approximately 0.67.
Since we can't sell a fraction of a cup, we would need to round up to the nearest whole number. Therefore, the least number of cups they need to sell in order to collect $10.00 more than they spend is 1 cup.
