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?
cents

50 cents

Step-by-step explanation:

The ratios can be added to find exactly how many of each coffees there are.

3 + 7 + 5 = 15

300 / 15 = 20

20 x 3 = 60 black coffees

20 x 7 = 140 sugared coffees

20 x 5 = 100 milk coffees

Multiply by the price.

60 x 50 = 3000 cents = $30 for black coffee

140 x 60 = 8400 cents = $84 for sugared coffee

100 x ? = 100? cents = $1? for milk coffee

Get rid of the ?.

164 - (30 + 84) = 50

$50 for milk coffee.

$1? = $50

? = $.50

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
