The double number line shows that 44 4 bottles of water cost 1010 10 dollars at a music festival. 00 0 44 4 bottles\text{bottles} bottles 00 0 1010 10 dollars\text{dollars} dollars based on the ratio shown in the double number line, how much does 33 3 bottles of water cost?

 7.5 dollar.

Step-by-step explanation:

Since, here the cost of 4 bottle of waters = 10 dollars.

Therefore, the cost of 1 bottle of waters = =

Thus, the cost of 3 bottle =

=

= 7.5 dollars.

So, the cost of 3 bottle is equals to $ 7.5.

because they could drop even lower..

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
