Answer:
It would cost 15600 to provide coffee for the whole year.
Explanation:
Given:
If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40
Now, to find the cost to provide coffee for the whole year if you're place is open 5 days a week.
So, we have the unit rate, and we have to find the cost of 1.5 cup by multiplying 0.40.
1.5 cup of coffee cost
![1.5* 0.40=0.60.](https://img.qammunity.org/2021/formulas/mathematics/high-school/g37cnhhfwwje2qvdealmfs4kwb4o1ytulj.png)
Thus, 1.5 cup cost 0.60.
If, 100 people drink 1.5 cups.
Then, total cost of 100 people drinking 1.5 cups of coffee =
![100* 0.60=60](https://img.qammunity.org/2021/formulas/mathematics/high-school/1mzrdjgs0119zx5i7zwrao4o0ktga0758v.png)
As, place is open 5 days a week.
So, to get the cost of coffee in 5 days of a week we multiply 5 by 60:
![5* 60\\\\=300.](https://img.qammunity.org/2021/formulas/mathematics/high-school/k90k0o1id0mjkqyzw6auxb73ik7lkr9f1h.png)
Hence, the cost of coffee in a week is 300.
In 1 year there are 52 weeks.
Now, to get the cost for the whole year we multiply 52 by 300:
![52* 300\\\\=15600.](https://img.qammunity.org/2021/formulas/mathematics/high-school/8797f9jzh7g1wqwku0blkz27p5d3zo3k9o.png)
Therefore, it would cost 15600 to provide coffee for the whole year.
