Raeann received $60 more pocket money than Irene each month. Both of them spent $140 per month and saved the rest. After a few months, Raeann saved $1560 but Irene only saved $1200.

1. What was Raeann's monthly pocket money?
2. Irene wanted to save a total of $2400. How many more months did she need in order to save this amount?

(a)
Total amount that Raeann saved more than Irene
= 1560 - 1200
= $360

Number of months taken for each of them to save their amounts
= 360 ÷ 60
= 6

Amount that Raeann saved each month
= 1560 ÷ 6
= $260

Raeann's monthly pocket money
= 260 + 140
= $400

(b)
Irene's monthly pocket money
= 400 - 60
= $340

Amount that Irene saved each month
= 340 - 140
= $200

Remaining amount that Irene needed to save
= 2400 - 1200
= $1200

Number of more months that Irene needed to save the remaining $1200
= 1200 ÷ 200
= 6

Answer(s): (a) $400; (b) 6
