Answer 1

To find out how many tablespoons of sugar Joanna should use for 1 cup of lemon juice, set up a proportion. Hence the correct answer is option A

Step-by-step explanation:

To find out how many tablespoons of sugar Joanna should use for 1 cup of lemon juice, we can set up a proportion. The recipe calls for 3½ tablespoons of sugar for every ½ cup of lemon juice. So, if we want to find the amount of sugar for 1 cup of lemon juice, we can set up the proportion:

3½ tablespoons / ½ cup = x tablespoons / 1 cup

Cross multiplying, we get:

3½ tablespoons * 1 cup = ½ cup * x tablespoons

x = 7 tablespoons

Hence the correct answer is option A
