Step-by-step explanation:

In the above question, we are given an inequality equation

7x + 50 > 4x + 100

To find the best expression that represents this equation we would analyse the 4 options that we were given

a) Molly has $50 and Mary has $100. Molly saves $4 per week and Mary saves $7 per week. How long will it be before Molly has more money than Mary?

Let the number of weeks money is saved be represented by x

Hence,

Molly > Mary

4x + 50 > 7x + 100

Option a) is Incorrect

b) Molly has $50 and Mary has $100. Molly saves $7 per week and Mary saves $4 per week. How long will it be before Molly has more money than Mary?

Let the number of weeks money is saved be represented by x

We are asked how long will it be before Molly has MORE MONEY THAN Mary , the inequality sign >

Hence,

Molly > Mary

7x + 50 > 4x + 100

This option matches the sceneraio in the question. It is correct

c) Molly has $50 and Mary has $100. Molly saves $4 per week and Mary saves $7 per week. How long will it be before Molly and Mary have the same amount of money?

Let the number of weeks money is saved be represented by x

We are told the same amount of money , the inequality sign =

Hence,

Molly = Mary

4x + 50 = 7x + 100

This option does not match the sceneraio in the question. It is Incorrect

d).Molly has $50 and Mary has $100. Molly saves $7 per week and Mary saves $4 per week. How long will it be before Molly and Mary have the same amount of money?

Let the number of weeks money is saved be represented by x

We are told the same amount of money , the inequality sign =

Hence,

Molly = Mary

7x + 50 = 4x + 100

This option does not match the sceneraio in the question. It is Incorrect

Therefore, only Option b) match the sceneraio in the above y.
