This question is too hard

Answer 1

7.50 is the answer to the question

Answer 2

$7.50 for 3 bottles of water.

Explanation:

It is given that 4 bottles of water costs $10. Find the unit price per bottle of water, by simply dividing 4 from both the bottle of water as well as the cost:

(4 bottles of water/$10)/(4/4) = (1 bottles of water/(10/4)) = 1 bottles of water/2.5

Each bottle costs $2.50

Check. Multiply the unit price per amount of units bought:

2.50 x 4 = 10

Next, find the unit price for 3 bottles. Multiply the unit price with the amount of bottles bought:

$2.50 x 3 = $7.50

$7.50 is your answer.
