Answer 1

Answer

15 bottles cost $7.5

Explanation

6 bottles of homemade lemonade costs $3

Let the cost of 15 bottles be x dollars.

6 bottles = 3 dollars

15 bottles = x dollars

We can write a mathematical relationship by cross multiplying

(6) (x) = (15) (3)

6x = 45

Divide both sides by 6

(6x/6) = (45/6)

x = $7.5
