Answer:
<em>2 scoops of fruity powder:6 cups of water will not test the same as Amar's recipe</em>
Step-by-step explanation:
<u>Ratios</u>
The proportion or ratios between variables measure the relative quantities of them by doing a division, usually expressed as fractions or a colon-separated pair of numbers.
To make fruit punch, Amar mixes 1 scoop of fruity powder with 5 cups of water. The ratio of fruity powder to water is 1:5.
We must select which recipe from the list won't produce the same ration and therefore will not taste the same as Amar's:
2 scoops of fruity powder:6 cups of water gives a ratio of 2:6. Simplifying by 2, the ratio is 1:3. This recipe will not test the same as Amar's.
2 scoops of fruity powder:10 cups of water gives a ratio of 2:10. Simplifying by 5, the ratio is 1:5. This recipe will test the same as Amar's.
0.5 scoop of fruity powder:2.5 cups of water gives a ratio of 0.5:2.5. Multiplying by 2, the ratio is 1:5. This recipe will test the same as Amar's.
5 scoops of fruity powder:25 cups of water gives a ratio of 5:25. Dividing by 5, the ratio is 1:5. This recipe will test the same as Amar's.
Answer:
2 scoops of fruity powder:6 cups of water will not test the same as Amar's recipe

Answer:
x=-20
Step-by-step explanation:
Just put the x on the other side of the equation
<h3>
Answer:</h3>
50 people
<h3>
Step-by-step explanation:</h3>
Let x represent the number of people on the cruise. The amount they each must pay is ...
... ($58 -(x -42)) = $100 -x
The revenue from the group is the product of the number of people and the amount each pays:
... r(x) = x·(100 -x)
This describes a downward-opeing parabola with zeros at x=0 and x=100. The vertex (maximum) will be found halfway between those zeros, at x=50.
A group size of 50 maximizes revenue from the cruise.
