Find the rate of money collected per sweatshirts sold. Show your work
I don’t know put can you help me :)
If your table has rows that look like
3 12
5 60
8 ___
___ ___
12 180
Not sure what to do. The ratio of sales and money is not constant.
If we try to use the three complete lines to form a quadratic function, then we get
y = 4/21 (-16x^2 + 158x - 375)
Somehow I don't think that's what you're after ...
To find the rate of money collected per sweatshirt sold, we need to divide the total money collected by the total number of sweatshirts sold.
Looking at the table, we can see that there are three sets of data: the number of sweatshirts sold, the money collected, and two blank cells.
To find the total number of sweatshirts sold, we can add up the numbers given in the first row of the table: 3 + 5 + 8 + blank + 12.
Similarly, to find the total amount of money collected, we can add up the numbers given in the second row of the table: 60 + blank + blank + 180 + blank.
Since two of the cells are blank, we need to find the values in those cells. From the given information, we can see that the number of sweatshirts sold and the money collected have a linear relationship. So, we can find the missing values using the known values.
To find the missing value in the first row, we can subtract the sum of the known values from the total number of sweatshirts sold: (3 + 5 + 8 + blank + 12) - total number of sweatshirts sold = blank.
Similarly, to find the missing values in the second row, we can subtract the sum of the known values from the total money collected: (60 + blank + blank + 180 + blank) - total money collected = blank.
Once we have filled in the missing values in the table, we can calculate the rate of money collected per sweatshirt sold by dividing the total money collected by the total number of sweatshirts sold.
Let's solve it step by step:
1. Add up the known values in the first row: 3 + 5 + 8 + 12 = 28.
2. Subtract the sum of the known values from the total number of sweatshirts sold to find the missing value: total number of sweatshirts sold - 28 = blank.
3. Add up the known values in the second row: 60 + 180 = 240.
4. Subtract the sum of the known values from the total money collected to find the missing values: total money collected - 240 = blank.
5. Once the missing values have been filled in, calculate the rate of money collected per sweatshirt sold: total money collected / total number of sweatshirts sold.
By following these steps, you will be able to find the rate of money collected per sweatshirt sold.
