Question

Nick has $40 and spends $1.50 each day. Bob has only $9 but he gets a daily allowance from which he saves $1.50 each day. In how many days will Bob have more money than Nick?

Answer 1

Nick.
40 - 1.50
38.5 - 1.50
37 - 1.50
35.5 - 1.50
34 - 1.50
32.5 - 1.50
31 - 1.50
29.5 - 1.50
27 - 1.50
25.5 - 1.50
= 24. 10 days.
24 - 1.50
= 22.5 after 11 days.
Bob:
9 + 1.50
10.50 + 1.50
12 + 1.50
13.50 + 1.50
15 + 1.50
16.50 + 1.50
18 + 1.50
19.50 + 1.50
21 + 1.50
22.50 + 1.50
Same amount of money: 24. After 10 days.
25.50 + 1.50
Bob will have more money then Nick in 11 days. He'll have 27 dollars when Nick has 22.5 dollars.
