Explain how you solved the problem.

Answer 1

Stephen has just enough lemon juice remaining after making 4 glasses of lemonade to make 4 glasses of iced tea, using all of the remaining 8 teaspoons of juice.

Step-by-step explanation:

To determine if Stephen has enough lemon juice to make 4 glasses of iced tea after making 4 glasses of lemonade, we must first calculate the total amount of lemon juice used for the lemonade. Since each glass of lemonade requires 5 teaspoons of juice, and he makes 4 glasses, the total amount used for lemonade is:

5 teaspoons/glass × 4 glasses = 20 teaspoons.

Stephen started with 28 teaspoons of lemon juice, so after making lemonade, he has:

28 teaspoons - 20 teaspoons = 8 teaspoons of lemon juice remaining.

Now, we need to examine if this remaining lemon juice is enough for 4 glasses of iced tea, with each glass requiring 2 teaspoons:

2 teaspoons/glass × 4 glasses = 8 teaspoons.

Yes, Stephen has just enough lemon juice to make 4 glasses of iced tea.
