OlgaM077 [116]

Answer:

16oz bag, $0.32 saved

Step-by-step explanation:

3.12/12 = 0.26

3.84/16 = 0.24

For the 12-ounce bag, it would be $0.26 per ounce. For the 16-ounce bag, it would only be $0.24 per ounce.

16*0.26=4.16

4.16 - 3.84 = 0.32

$0.38 saved

The ratio of the sales of black coffee to sugar coffee to milk coffee is
Ann [662]

Answer:

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
