Question

Alyssa's lemonade recipe calls for 9 lemons for every 2.5 gallons
of water. Brian's recipe calls for 12 lemons for every 4 gallons of
water. Whose lemonade will require more water if they each use
36 lemons?​

Answer 1

Brian's recipe of lemonade requires more water than Alyssa's lemonade recipe.

Step-by-step explanation:

For Alyssa's recipe,

2.5 gallons of water needed for 9 lemons.

So for 36 lemons, $\frac{2.5\times 36}{9}$   = 10 gallons of water needed

For Brian's recipe,

4 gallons of water needed for 12 lemons,

So for 36 lemons, $\frac{4\times 36}{12}$  = 12 gallons of water needed.

So Brian's recipe needs more water when compared to Alyssa's recipe.

Answer 2

Answer: Brian's lemonade recipe requires more water.

Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.
