Question

The ratio of the sales of black coffee to sugar coffee to milk coffee is 3:7:5. The total sales of the three coffees is 300 cups. Each cup of black coffee costs 50 cents and each cup of sugared coffee costs 60 cents. If the earnings from the total sales was $165, what is the price of each cup of milk coffee?

Answer 1

Answer = $55
Because 3 + 7 + 5 = 15
The 3 = black coffee
The 7 = sugar coffee
And the 5 = milk coffee
So then u do 5/15 simplified = 1/3
So then do 1 /3 of $165 = $55
