Answer:

Box of Popcorn: $3.00

Drink: $2.00

Step-by-step explanation:

If we input the prices into the original problem it would be something like this, (2)3.00 + (3)2.00 = $12.00 (3+3 = 6 and 2 + 2 + 2 = 6 6+6= 12) Or 2x + 3x = $12

And you would do the same thing for the second one.

(3)3.00 + (5)2.00 = $19.00 ( 3 + 3 + 3 = 9 and 2 + 2 + 2 + 2 +2 = 10 10+9= 19) Or 3x + 5x = $19

Sorry if it's incorrect but i hope it helps!

Which ratio is porportional to 18/21? A.2/3 B. 30/35 C. 36/48 D.1/3
defon
You can solve this problem by applying the proccedure below:
 
 You have:
 
 a) 18/21=2/3
 18x3/21x2
 36≠42 (2/3 is not proportinal to 18/21).
 
 b)18/21=30/35
 18x35/21x30
 630=630  (30/35 is proportional to 18/21)
 
 c)18/21=36/48
 18x48/21x36
 864≠756  (36/48<span> is</span><span> not proportinal to 18/21)
</span> 
 d)18/21=1/3
 18x3/21x1
 54≠21  (<span> 1/3 is</span><span> not proportinal to 18/21)
</span> 
 Therefore, you can conclude that the correct option is: B.30/35
