cup plaster of paris.
Number of bathes = 3
We need to find quantity of plaster of paris.
Solution:
For making 1 batch of sidewalk chalk =
cup plaster of paris.
For making 3 batches of sidewalk chalk =
cup plaster of paris.
![= 3\times \frac{2\times 1+1}{2}](https://tex.z-dn.net/?f=%3D%203%5Ctimes%20%5Cfrac%7B2%5Ctimes%201%2B1%7D%7B2%7D)
![= 3\times \frac{2+1}{2}](https://tex.z-dn.net/?f=%3D%203%5Ctimes%20%5Cfrac%7B2%2B1%7D%7B2%7D)
![= 3\times \frac{3}{2}](https://tex.z-dn.net/?f=%3D%203%5Ctimes%20%5Cfrac%7B3%7D%7B2%7D)
![= \frac{3\times 3}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B3%5Ctimes%203%7D%7B2%7D)
![= \frac{9}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B9%7D%7B2%7D)
![=4\frac{1}{2}](https://tex.z-dn.net/?f=%3D4%5Cfrac%7B1%7D%7B2%7D)
Therefore, he needed
cups plaster of paris.
That question is impossible because we don’t know what we are trying to solve for it has to be x or y in this scenario it can’t be both we need one to find the other
