Answer (2)
Hello,
x= number of months that it takes for David and Louis to have equal amounts of money.
Then:
140 + x ∗ 150 = 260 + x ∗ 120 150 x − 120 x = 260 − 140 30 x = 120 x = 4
Answer: it takes 4 months --> OPTION B
David and Louis will have equal amounts in their bank accounts after 4 months. Therefore, the answer is OPTION B.
