Victoria received $30 more pocket money than Kimberly each month. Both of them spent $150 per month and saved the rest. After a few months, Victoria saved $1690 but Kimberly only saved $1300.

1. What was Victoria's monthly pocket money?
2. Kimberly wanted to save a total of $2200. How many more months did she need in order to save this amount?

(a)
Total amount that Victoria saved more than Kimberly
= 1690 - 1300
= $390

Number of months taken for each of them to save their amounts
= 390 ÷ 30
= 13

Amount that Victoria saved each month
= 1690 ÷ 13
= $130

Victoria's monthly pocket money
= 130 + 150
= $280

(b)
Kimberly's monthly pocket money
= 280 - 30
= $250

Amount that Kimberly saved each month
= 250 - 150
= $100

Remaining amount that Kimberly needed to save
= 2200 - 1300
= $900

Number of more months that Kimberly needed to save the remaining $900
= 900 ÷ 100
= 9

Answer(s): (a) $280; (b) 9
