Question

Can someone help me? Kendall owns 39 CD’S, and he buys a new one every week. Raymond only owns 15 CD’S but he buys 3 new ones each week. How many weeks will it be before Raymond owns as many CD’S as Kendall?

Answer 1

Answer:

• 7 weeks

Step-by-step explanation:

Let the number of weeks be x

Then Kendal's CD's

• 39 + x

Raymond's CD's

• 15 + 3x

Time when they have equal CD's

• 39 + x = 15 + 3x
• 3x - x = 39 - 15
• 2x = 14
• x = 7 weeks
