For this problem we have the following info given:
Cups of coffee= 25 Glasses of orange juice= 10 Omelets= 6
We want to estimate how many glasses of orange juice does the restaurant expect to sell in 1 hour.
We know that the restaurant sell 10 glasses of orange juice every 15 min and we can create the following proportional rule since we know that in 1 hour we have 60 minutes.
![(10glasses)/(15\min utes)=\frac{x}{60\text{minutes}}](https://img.qammunity.org/2023/formulas/mathematics/college/irurc2fgk3e2zstm2xqf79fv3zqwnqftdi.png)
Where x represent the number of glasses of orange juice in 60 minutes=1 hour. And if we solve for x we got:
![x=60\cdot(10)/(15)=40glasses](https://img.qammunity.org/2023/formulas/mathematics/college/7w2n3ke65jexid9uwnbr85hq2yo0f7t604.png)
And we can conclude that the restaurant expect 40 glasses of orange juice every 1hour=60 minutes.
