Answer:
It would cost <u>15600</u> to provide coffee for the whole year.
Step-by-step 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.
<em>1.5 cup of coffee cost </em>![1.5\times 0.40=0.60.](https://tex.z-dn.net/?f=1.5%5Ctimes%200.40%3D0.60.)
<em>Thus, 1.5 cup cost 0.60.</em>
<em>If, 100 people drink 1.5 cups.
</em>
<em>Then, total cost of 100 people drinking 1.5 cups of coffee = </em>
<em />
<em>As, place is open 5 days a week.</em>
So, to get the cost of coffee in 5 days of a week we multiply 5 by 60:
![5\times 60\\\\=300.](https://tex.z-dn.net/?f=5%5Ctimes%2060%5C%5C%5C%5C%3D300.)
<em>Hence, the cost of coffee in a week is 300.</em>
<em>In 1 year there are 52 weeks.</em>
Now, to get the cost for the whole year we multiply 52 by 300:
![52\times 300\\\\=15600.](https://tex.z-dn.net/?f=52%5Ctimes%20300%5C%5C%5C%5C%3D15600.)
Therefore, it would cost 15600 to provide coffee for the whole year.
