Julie received $40 more pocket money than Irene each month. Both of them spent $190 per month and saved the rest. After a few months, Julie saved $1560 but Irene only saved $1400.

1. What was Julie's monthly pocket money?
2. Irene wanted to save a total of $2100. How many more months did she need in order to save this amount?

(a)
Total amount that Julie saved more than Irene
= 1560 - 1400
= $160

Number of months taken for each of them to save their amounts
= 160 ÷ 40
= 4

Amount that Julie saved each month
= 1560 ÷ 4
= $390

Julie's monthly pocket money
= 390 + 190
= $580

(b)
Irene's monthly pocket money
= 580 - 40
= $540

Amount that Irene saved each month
= 540 - 190
= $350

Remaining amount that Irene needed to save
= 2100 - 1400
= $700

Number of more months that Irene needed to save the remaining $700
= 700 ÷ 350
= 2

Answer(s): (a) $580; (b) 2
