Total sales of this year = Total sales of last year + sales increased
![5713.340 = x + x * 35\%\\5713.340 = x + (35x)/(100) \\5713.340 = (135x)/(100) \\](https://img.qammunity.org/2021/formulas/mathematics/middle-school/w6w4qitgetpys5bcd8pxuie8zxw7nhxgw3.png)
Multiplying both side by 100
![571334 = 135x\\](https://img.qammunity.org/2021/formulas/mathematics/middle-school/fa86y1i7a58oaszl0r8ecz7o2fmr9n72vf.png)
Dividing both side by 135
![4232.10 = x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/je87vxieeel19r69bdn3cj7ihu5tdetg6k.png)
Therefore, the amount of last years sales is 4232.10
