Write your answer using a percent sign (%).

Answer 1

Joey's Cafe sold 20% regular coffee and 80% decaffeinated coffee.

Explanation:

We are given that the cafe served 35 coffees. We are also told that of those 35 coffees, 7 coffees were regular.

Therefore, we can divide the number of regular coffees by the total number of coffees sold to get the percentage of regular coffees.

Our ratio will be set up as 7 regular coffees : 35 total coffees. We can also represent this as a fraction.

`\displaystyle(7)/(35)=(1)/(5)\\\\(1)/(5)=0.2\\\\0.2 * 100 = 20\%`

Therefore, of the coffees sold at the cafe, 20% of those coffees were regular.

Additionally, we can subtract this percentage from 100 to find out how much of the sales were decaffeinated coffee.

`100\% - 20\% = 80\%`

Joey's Cafe sold 80% decaffeinated coffee.
