50 dollars per month. It says "after x months" -50x is the variable thats changes.
For example: if the word problem were simply "4 divided by 2", the fraction would be a 4 with a line underneath and the 2 underneath that.
I hope I made this possible to understand... let me know if you were referring to something else!
I assume the rug is rectangle.
The area of rectangle is width (W) multiply by hight (H)
![A=4\frac{15}{36}=4\frac{5\cdot3}{12\cdot3}=4\frac5{12}\\\\H=2\frac34\\\\\\A=W\cdot H\\\\4\frac{5}{12}=W\cdot2\frac34\\\\4\frac5{12}:2\frac34=W\\\\ \frac{4\cdot12+5}{12}:\frac{2\cdot4+3}{4}=W\\\\ \frac{53}{12}:\frac{11}4=W\\\\ \frac{53}{12}\cdot\frac4{11}=W\\\\ \frac{53\cdot4}{3\cdot4\cdot11}=W\\\\W=\frac{53}{33}\\\\W=1\frac{20}{33}](https://tex.z-dn.net/?f=A%3D4%5Cfrac%7B15%7D%7B36%7D%3D4%5Cfrac%7B5%5Ccdot3%7D%7B12%5Ccdot3%7D%3D4%5Cfrac5%7B12%7D%5C%5C%5C%5CH%3D2%5Cfrac34%5C%5C%5C%5C%5C%5CA%3DW%5Ccdot%20H%5C%5C%5C%5C4%5Cfrac%7B5%7D%7B12%7D%3DW%5Ccdot2%5Cfrac34%5C%5C%5C%5C4%5Cfrac5%7B12%7D%3A2%5Cfrac34%3DW%5C%5C%5C%5C%20%5Cfrac%7B4%5Ccdot12%2B5%7D%7B12%7D%3A%5Cfrac%7B2%5Ccdot4%2B3%7D%7B4%7D%3DW%5C%5C%5C%5C%20%5Cfrac%7B53%7D%7B12%7D%3A%5Cfrac%7B11%7D4%3DW%5C%5C%5C%5C%20%5Cfrac%7B53%7D%7B12%7D%5Ccdot%5Cfrac4%7B11%7D%3DW%5C%5C%5C%5C%20%5Cfrac%7B53%5Ccdot4%7D%7B3%5Ccdot4%5Ccdot11%7D%3DW%5C%5C%5C%5CW%3D%5Cfrac%7B53%7D%7B33%7D%5C%5C%5C%5CW%3D1%5Cfrac%7B20%7D%7B33%7D)
