Question

Edward has $400 more than Robert. After Edward spends $60 on groceries, he has three times more money than Robert. How much money does Robert have?

Answer 1

Answer: 170

Step-by-step explanation:

We can set up simultaneous equations such that:

E = R+400

E - 60 = 3R

Solving gives R = 170 and E =570

Answer 2

Answer:

Robert has $140

Step-by-step explanation:

400 - 60 = 420

420/3 = 140
