A recipe for tropical punch calls for 2 22 cups of pineapple juice and 3 33 cups of orange juice. Jo creates a drink by mixing 3
Murrr4er [49]

<u>Situation 1: Recipe for tropical punch</u>

Number of cups of pineapple juice = 2.

Number of cups of orange juice = 3.

Total number of cub of juice = 2+3 = 5 cups.

Let us find % of pineapple and orange juice in total number of cups of juice.

% of pineapple = 2/5 = 0.40 = 40%.

% of orange juice = 3/5 = 0.60 = 60%.

<u>Situation 2: Jo's drink</u>

Number of cups of pineapple juice = 3.

Number of cups of orange juice = 4.

Total number of cub of juice = 3+4 = 7 cups.

Let us find % of pineapple and orange juice in total number of cups of juice.

% of pineapple = 3/7 = 0.429 = 42.9%.

% of orange juice = 4/7 = 0.0.571 = 57.1%.

Please note: <u><em>In Jo's drink pineapple juice % increased and orange juice %  decreased by the tropical punch recipe.</em></u>

<h3>Therefore, Jo's drink will have a stronger pineapple taste.</h3>

pickupchik [31]
No because she's adding ounces plus 2 pounds so she's up to 54 pounds so... plus the 12 ounces and 8 ounces, and 12 ounces into 1 pound would be 0.75 so it's almost a pound....then 8 ounces into a pound would be 0.5 pounds so if you add the two 0.75 and 0.5 you would get 1.25 pounds... so 1.25 plus 54 pounds would not be 56 pounds...So No. Please mark brainliest:)!
