Question

Nathan and Jackson are each saving money.

Nathan has $15 saved and plans to save $5 more each week.
Jackson has $25 saved and plans to save $4 more each week.
How many weeks will it be before both boys have saved the same amount of money?
5
7
8
10

Answer 1

• D) 10

-----------------------

Let the number of weeks be w.

Nathan will have:

• 15 + 5w

Jackson will have:

• 25 + 4w

Since amounts are same, set them equal:

• 15 + 5w = 25 + 4w
• 5w - 4w = 25 - 15
• w = 10

After 10 weeks they will have saved the same amount.

This is option D.
