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 = $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
