3 Bottles of water would cost $7.50. Since 4 water bottles cost $10, then you do 10 divided by 4 and get 2.5. $2.50 is how much one bottle of water costs. So you do 2.5 times 3 to get the answer.

[tex]10 \div 4 = 2.5 \\ 2.5 \times 3 = 7.5[/tex]

Answer:

The 3 bottles of water will cost:

                         $ 7.5

Step-by-step explanation:

It is given that:

4 bottles of water cost 10 dollars at a music festival.

This means that 1 bottle of water will cost:

Cost of 4 bottles/4= $ (10/4)=$ (5/2)

Hence, the cost of 3 bottles will be:

cost of 1 bottle×3

=   $ (5/2)×3

= $ (15/2)

= $ 7.5

Hence, the cost of three bottles of water will be: $ 7.5
