Answer:
![T = R](https://tex.z-dn.net/?f=%20T%20%3D%20R)
![925 +0.05 x = 1250 +0.03 x](https://tex.z-dn.net/?f=%20925%20%2B0.05%20x%20%3D%201250%20%2B0.03%20x)
Subtracting 0.03x from both sides we got:
![925 +0.02 x = 1250](https://tex.z-dn.net/?f=%20925%20%2B0.02%20x%20%3D%201250)
And now subtracting 925 from both sides we got:
![0.02 x = 325](https://tex.z-dn.net/?f=%200.02%20x%20%3D%20325)
And dividing by 0.02 both sides we got:
![x = 16250](https://tex.z-dn.net/?f=%20x%20%3D%2016250)
So then we need a total 16250 for the amount of sales in order to have the same amount for Ramon and Teresa at the end of the week
Step-by-step explanation:
For this case we can assume that the total salary for Teresa T is given by:
![T = 925 + 0.05 x](https://tex.z-dn.net/?f=%20T%20%3D%20925%20%2B%200.05%20x)
Where x represent the amount of sales. And similarly for the total salary of Ramon we have:
![R = 1250 +0.03 x](https://tex.z-dn.net/?f=%20R%20%3D%201250%20%2B0.03%20x)
We want to find what amount of sales, x, will result in each of them earning the same amount for the week and we can set up the following equation:
![T = R](https://tex.z-dn.net/?f=%20T%20%3D%20R)
![925 +0.05 x = 1250 +0.03 x](https://tex.z-dn.net/?f=%20925%20%2B0.05%20x%20%3D%201250%20%2B0.03%20x)
Subtracting 0.03x from both sides we got:
![925 +0.02 x = 1250](https://tex.z-dn.net/?f=%20925%20%2B0.02%20x%20%3D%201250)
And now subtracting 925 from both sides we got:
![0.02 x = 325](https://tex.z-dn.net/?f=%200.02%20x%20%3D%20325)
And dividing by 0.02 both sides we got:
![x = 16250](https://tex.z-dn.net/?f=%20x%20%3D%2016250)
So then we need a total 16250 for the amount of sales in order to have the same amount for Ramon and Teresa at the end of the week
