Required
Determine the day to week rate
This can be calculated by dividing the daily medicine cups by the weekly cups;
![Rate = (Daily)/(Weekly)](https://img.qammunity.org/2021/formulas/mathematics/high-school/gg48i2sx6041wrmr7xvlgchdubep9cv9iv.png)
Substitute 500 for Daily and 4000 for Weekly
![Rate = (500)/(4000)](https://img.qammunity.org/2021/formulas/mathematics/high-school/jgkjt2lettk8a9ttpk0zr7u722na6qfh17.png)
![Rate = 0.125](https://img.qammunity.org/2021/formulas/mathematics/high-school/tdegkqr4yg8tmobzt7l6b80dbpk3t4cmzl.png)
Hence, the rate of the daily to weekly medicine cup is 0.125
